On a Google search fit tailgate lock 79 Malibu that’s what comes up although Dorman lists it as fitting S-10 Blazer and Bravada. The part pictured looks the same as my part so I give it a try and post back. Here are pics to compare

If you're good at rebuilding these things, you can get the pieces parts to do it.

Outer case, that the keyed guts slips into, should you need it, is GM p/n 3064840.

The twisty handle with the tumbler bits is 9632765. Return spring is unobtainum, p/n 3070489. Tumblers , tumbler springs (GM p/n 3901067, strattec 46648), and tumbler retainers (GM p/n 601261) are typical old-school GM junk. O-ring (gasket) shows GM p/n 3065573 or it also could be 3066550, and the rear gasket seems to be unobtanium as well. If anyone has exact dimensions (assuming it's notched), I MAY can cut one on my plotter/cutter thingie I use for decals.

GM p/n 9632765 typically uses a B key slot (key slot requirement stamped on the key). It was superseded by GM p/n 12507441 in the early 90s, so I'm guessing it MIGHT be a different keyslot. Below's a kit on ebay consisting of the handle cylinder and sleeve. The hardest part about these **** GM locks is that the key slot COULD and DID change over the years. So depending on date of manufacture, it will determine which key you need. You don't even want to know how long it took me to get a correct NOS "A" keyed ignition lock. Most are E and C.

3064843 for the pawl.

Kit on ebay is the best way to get tumlbers. GM sold them by the 100 box. WAY too many. You'd have 500 tumblers just to be able to rekey a lock correctly with any tumblers.

Just an option. :)

Wow! Talk about a lesson in futility. I must say this thread has been educational. I agree, it should be made a sticky.
JD, I didn't think to ask you if you had a rear glass release. I guess I was assuming that you didn't. As the old adage goes, don't assume anything.
Also, great job on the emergency release setup. My hat's off to you. :friday:

Honestly, I may have recognized the release button at some point in the past. If I had, it obviously slipped my mind. 😑

Yeah, the one that came on the car when we got it was the original chrome one. It had been drilled so the gate part is no longer there.

As far as the replacement being black instead of chrome, that's not a big deal for this car. The car is a rag tag survivor with cookie sheets patching floor pans, swiss cheese door sills coated in POR-15, about 11lbs of bondo all the way down the passenger side, I could go on but you get the point. Primer being the perfect color of choice for a car like this

Even with the rough condition overall, it's a fun reliable driver that turns heads and frequently has people asking, "is that car for sale?" the answer is always no.

I can confirm the Dorman 77101 lock cylinder with wings assembly which is listed for S-10 Blazer and Olds Bravada tailgates works in G body wagons. Here’s a demonstration video.

I just read this whole thing at once so my recommendation isn't necessary anymore, but I was going to suggest using a universal T-Handle choke cable for a release if a regular trunk or hood release cable didn't fit. I'm also a fan of using acetone and transmission fluid as a penetrating lube since the acetone makes it really creep. Amazing that the electric release was hiding there the whole time, that's a lucky break.
