Good quality for the money spent.
Tried a cheaper one last time that froze up and locked the column. This one is a step up and so far is working ok. Make sure and use liquid wrench on all the moving parts inside the column. That includes the switch too.

Perfect fit. Can’t go wrong with AC Delco

Great fit! No problems at all going in 73 Vette
I had read on various sites that not all of these are created equal. The short of it was that many of them were just slightly off or had burs in places that made it difficult to put these in place. So when I pulled this out of the box, walked up to the car, and this bad boy slid right in I was ecstatic! Fit and finish was better than what it replaced (granted the original was 40+ years old too). So long story made short - for my application in a 73 Vette this item was dead on perfect!

GM Quality, OE awesome
I looked everywhere for AC Delco GM quality. This key lock is amazing, as nice as the 32 year old original. Says GM on key, Chrome handle, snap in style. In 1978, GM transitioned from snap in to bolt in lock cylinders. You must use the right one. I removed my lock first to confirm, ordered this on and got in 3 days. In AC Delco box, Highly recommended. Might be a couple bucks more than Dorman or knockoffs. Buy this one for 1978 and earlier GM.

Works great on my 1978 El Camino
The old ignition switch was so worn you didn't even need a key to start the car so I figured while I was replacing the turn signal switch I would replace this as well. It was very easy. Just push the lever in and boom the ignition slides out. Popped the new one in with ease. It didn't work every time when I first installed it but the seller suggested a bit of lube so I sprayed a touch of wd40 on the cylinder and a touch in the key hole and works every time now.

It is great to have a working ignition cylinders
I have used this on both my AMC Concord and my Chevrolet K20 (both have the same steering column), It is great to have a working ignition cylinders. The original cylinders on both the Concord and K20 were worn and you could start the vehicles without the key. The new lock cylinders were easy to install and work great.... now if only there was an easy way to tell the difference between the two keys. hehe
