Worn hatch pin receiver? [not the insert]

[maint]

I have been seemingly forever adjusting my rear hatch pin receivers (rear lid lock). I installed new pins and the inserts from 944online a while back. I did need to sand the inserts a bit to fit the new pins. I now think the back of the lock 'jaws' are worn out but would like a second opinion.
I have the lock out of the car and have tried it on both pins and a older spare pin. The jaws close around the pin ok, but I can pull it off easily, squarely, without wiggling. Even if I try to hold the arm so the jaws clamp it will come off. I had a bad spare and opened it to look inside. The back of the jaws have a 'tapered' edge that pries the jaws open under nominal force. After a close look at the one I'm using it looks to be the same. I don't know if that is worn away or there to aid latching.
Are they supposed to have a flat surface where they hold the pin?

I had an 84 open up on the high way, LOL! Talk about down force. Ha. My 86 opened up in a shopping strip mall, I didnt even know it was open, {loud rock and roll} untill somebody yelled, hey your trunk is open. A good friend showed me how to adjust the spikey latch knobs to keep it tight and keep it from opening...

It was not out of adjustment but worn out. I thought since it was no good anyways I may as well take it apart. I drilled the two 'rivets' that hold it together and got a good look at the jaws. They were definitely too worn to hold the pin. I built up the back side of the jaws with weld and filed it to shape (flat on back, slight taper on front so pin will slide in). Now I can't pull the pin out of the jaw without opening the latch arm.


opened up lock


worn out jaws. No way that tapered jaw can resist the pin being pulled out



Built up the back edge of the jaws with weld then filed to shape. Have the lock back together but not installed



Looking at the two spares I have, both show wear but not as bad as the one I repaired. Now I know what to look for if the Right one starts to release and I can't correct it with adjustment. If it seems like a lot of bother to fix the lock, the cheapest I could get one with shipping and exchange rate was $208

Yeah, those buggers aren't cheap. Nice work adding material; if it works as planned you'll be sitting pretty
