Worked on a 2004 with a little creative adjustment
Holefully this review will help others with a simialr year. I have a 2004 tj Sahara, my configuration was a little different than the instructions. In my picture I circled a t50 torx bolt in red that was what I assume a factory upgrade over previous years for the seat belt as this bolt is right under the mount. It's also 7/16-20 which is a little heavier than the other 3 bolts that bolt to the floorboard. I installed the drivers side brackets as close to the instructions as I could but the torx bolt presented the following issues. A. Would not go in with the brackets mounted, B. Had to drill a hole for the larger torx bolt. C. Could not tighten the torx bolt after the brackets were installed. I found it much easier on the passenger side to bolt the brackets down first with the seat mounting bolts installed then put the seat over the bolts and tighten. I drilled the brackets for the torx bolt to 1/2 in for a little flexibility. I went back and redid the drivers side and found out I had the brackets A1 and A2 I. The wrong position. In the picture there is a blue arrow, one of the mounting plates is a little smaller than the other 3, in the instructions they are labeled B1 B2 B3 and B4, the shorter one goes where the blue arrow is. The main brackets are labeled A1 and A2, and A2 is offset, i drew a yellow line to give you an idea of the offset. A2 goes closest to the shifter on driver and passenger sides. Putting these in first also helps with the placement and hole alignment. The odd thing is the factory jack no longer fits under the passenger seat as it should. It is secure but crooked. I also used the factory bolts to hold the brackets down. Iay go back and get some grade 8 to replace the chrome plated ones that came with the kit. I would suggest doing this, would hate to have the seat shear off in an impact. These brackets work great for a guy that's 6' 4" and now with more legroom I can comfortably get in and out as well as drive without being cramped. The tilt/tumble passenger seat still works as it did, but i dont think anyone will sit in the rear seat with me in a comfortable position. A good product, well made but not quite as universal as you would think.

Waste of money.
Absolute junk. Does not fit correctly. Bolt holes do not line up to seat base. You will have to drill one hole. It's not worth 38.00 the directions are absolute useless, the pictures are horrible. I may remove this junk, send it back and build my own.

Poor instructions, and not ready to install, but worth it!
Just like others have stated, a real pain to install with limited instructions to go by. I still have it 5 stars, excuse it made a huge difference in making leg room much more comfortable in my TJ. There are a couple of reviews others have left that get you in the ballpark after you drill the one hole. I feel as the others do, which is a piece of color coded or numbered tape on each piece and better instructions as well as all holes should be predrilled to the proper diameter to speed the process up.

THROW AWAY THE INSTRUCTION BUT IT WILL FIT.
It went in. DO NOT bother with the instructions. On my TJ there is one star bolt in the rear. You MUST drill out the bracket first or the star bolt will not go back in to secure to the frame. Start with bolting to the frame and then fit the seat. DO NOT fit the brackets to seat first. Finally the bent longer bracket goes closes to the passenger seat not the driver side door.

Modifications for passenger side and better hardware for both sides needed
This is on my 2003 Rubicon. I do love the additional leg room. The first 5 pictures show the passenger side. Yes I cut a square out of the frame to accommodate the T50 bolt (pic 1 and 4). I attached the bracket with the T50 in place on the work bench. Carefully marked when the frame needed to be cut. Drilled 4 small holes in each corner of the square I removed before using a dremel with a cut off wheel. I cut the “under side” brackets to fit where the curves of the seat bracket will need supporting. These got placed on top of the bracket. Also added a washer that was supplied with the kit on top of them before bolting down the seat. The thickness of the cut plate and the washer is all you’ll need. This was after carefully measuring the gap with a caliper. The passenger side seat needs this support on top of the bracket to function properly. Info about bolts below. Long ends of the brackets face the back on the passenger side. Long ends face the front of drivers side. Pic 5 shows plate placement. Pay attention to the placement of the shorter side plates. Angled brackets go next to the transmission tunnel (where your armrest is). I got a size up carriage bolts for both sides. Took the head of the bolts to a grinder to knock off a little bit of the dome. Not much, just a bit. The square of the carriage bolt will lock into the notches of the brackets. I got this idea after reading the installation instructions and watching a video on the BigBoy seat brackets that cost twice as much. They don’t have plates, just carriage bolts. I didn’t use the plates on the drivers side and have had no issues. Think these come with 1/4” bolts so I got 5/16” carriage bolts along with flat washers, lock washers and nuts.Beats fighting getting the supplied bolts to cooperate. The additional $20 +/- in hardware was worth it. Yes you will have to plan a bit to make these work. You I’ll need to drill or enlarge the oblong holes. Others have said they couldn’t get the jack back in: rotate the crank park of the jack towards the front. Have to reach in from the front to loosen and tighten it. My tire iron just floats under the seat. One day I may fabricate a new holder for it. Hope the painstaking 4 hours of planning and two trips to the hardware store helps someone in the future. Disclaimer: I am not responsible if you over cut your passenger seat and weaken it.

Works great, Don't believe all the negative installation reviews.
I placed an order for these and then started reading all the negativity in relation to the installation and all for not. Don't over think the simplicity of the design and installation and you will be just fine. Yes, you do have to enlarge two of the predrilled holes. This is the hole where the Torx bit nut is located, but if you will use a step bit, and secure the pieces that you are drilling on, go slow and don't try to speed drill, it's a piece of cake. FWIW, cheap step drill bits are available at Harbor Freight or Amazon. There are 2 large pieces of pre-formed metal each formed differently. The piece that has a few funky angles go to the inside next to the transmission tunnel/console. The other on the side closest to the door. Each piece of metal has a longer end before and after the formed bend. They do not both fit the same in that one piece when installed will be with the longer end forward and the other with the longer end the other direction, again don't try to over think the design as it does all come together and work perfectly. There are also 4 bottom plates that set underneath the longer metal pieces of the frame. One of these plates is shorter than the other 3, the shorter plate goes on the door side forward position. Also let me note that by flipping (top to bottom) these shorter plates it can made a difference in the hole alignment. And as others have pointed out, install the new framework to the Jeep first not to the seat frame. You can leave all the floor mounting bolts loose with the exception of the larger torx bolt which you will need to tighten before mounting the seat back in the Jeep due to accessibility once the seat has been reinstalled. If you need to move the back inward seat frame mounting blot to align with the hole in the seat frame you can use a long screwdriver and a hammer to move the bolt into position. Installation took me approximately 30 minutes which was time well spent. Well worth the time and money for the improvement it offers in the seating position. One last reminder, don't over think the installation or the design. The holes will align without use of force, you may simply clear your head and flip a piece to proper alignment of the holes, but they do align perfectly. ****I used the OEM bolt to anchor the framework to the Jeep and the supplied hardware for mounting the seat base to the extender. I will likely replace the supplied hardware that I used with a heavier grade choice of nuts and bolts in the future.

Took my time and it went in easy enough.
All of the reviews really helped when it came time for installation. I am 6'-6" and 220 pounds and I seriously needed the extra leg room. I read the really long and detailed review and it helped a lot. I still had to hog-out the holes on the inside bracket and the spacer (twice). I didn't realize I needed to hog it out closer to the backside of the brackets, so I took the seat out twice to get the exact fit I wanted. One thing I learned was to put some strong duct tape to hold the bolts in place on both back brackets so the bolts didn't fall out of the octagon holes of the spacer plates. Then I put a putty knife under each side to keep the seat bolts from pushing down when I was mounting the seat back in (by myself). Do yourself a favor and recruit some help. It does line up once you get everything in properly, but the instructions are very confusing. Very glad I purchased this seat bracket and appreciate everyone's reviews.

It almost just quite but didn't just barely fit. And that was the problem.
First the good stuff. This product fills a definite need. I am 6'5" and Jeeps were never built for guys like me. Chrysler should consider a second set of factory seat mounts further back like some European sports cars. (But that is another issue. Now that it is installed, the extra legroom is great. My right knee no longer bashes into the dash or knocks my USB adapter out of the power port. (You tall guys know what I'm talking about) Word of caution though. If even after installing the adapter you still need to push the seat all the way back, be aware your head will be right up against the roll bar. Mine is less than an inch away. In a rear-end collision this could be bad. But then again, you should never let anyone rear-end your Jeep. Now the bad stuff. I was planning to fabricate my own adapter. Looking for inspiration I stumbled upon this adapter and, for the price, decided to buy rather than build. Unfortunately like nearly all products these days it just isn't quite right. It almost fits. Close enough that with some modifications and a bit of persuasion you can make it work. This seems to be the way of modern aftermarket products. Maybe the car companies have a secret cabal to move things around a tiny bit every year so we will always go back to them for factory parts. But I doubt that. I'm more inclined to think that there isn't enough aftermarket parts testing. If the prototype fits, make a million of them. But I digress. Back to my review. The first problem I had is that there is no way to install the adapter on my 2005 TJ by following the instructions. In the real world, you must first mount the adapter in the Jeep and then mount the seat to the adapter. The instructions have it the other way around. This did not work for me. Once the adapter is on the seat you cannot access two of the four mounting holes at enough of an angle to get the bolts through the holes. And even if you could, good luck getting a socket on them to torque those suckers down. Therefore the only way to mount this adapter is to remember this little rhyme "First in the Jeep, then mount the seat". The second problem is that in my 2005 TJ the inboard rear bolt is larger than the others. Likely a safety thing since that is the corner the seatbelt anchors. But the hardware in the adapter kit is all the same size bolts. It would be simple enough to reuse your stock bolt 'except' the holes in the adapter are too small. You will need to drill out that hole, "waller it out" is probably the correct term. The final "problem" is there is an offset bend in one of the adapter rails to account for the asymmetrical seat mount hole spacing in the Jeep. This bend is critical and unfortunately, on mine, it just was not quite right. The result is once the adapter is mounted in the Jeep the rear seat mounting bolts don't quite line up with the holes in the seat. My solution was a Gorilla Bar and some steady lateral persuasion. Unfortunately, this slightly racks the seat slides, and they now bind a little. But I don't plan to move my seat much. I can live with it. In conclusion: Do I recommend this product? You might be surprised but Yes I do. For the price, it would be hard not to. But know what you are getting into. There will be a lot of cussing, some prying (I hope no crying), and in the end, your seat may not slide quite as smoothly as it did from the factory. Oh yeah, and watch your head on that roll bar. Don't say I didn't warn you.
