Default 1965 Pontiac GTO tail light socket

Hello all,

Little project I'm been completely stuck on. I bought LED 1157 bulbs for my tail light/brake light. Problem is my tail light socket is so old and weak the metal contacts don't even contact the LED bulb base. Easy fix normally, just replace the tail light sockets with new ones and good to go.

My problem is that the sockets that everyone says go to a 65 don't fit at all, they're entirely different sockets and not compatible. I tried the Wells version as well as the AC Delco version, neither of which work. I have included a photo of my sockets, vs what the internet is saying is correct. As you will see, they are entirely different parts. What makes this so frustrating is that I cannot even find proof of my socket's existence, other than my own. I cannot find a picture of the correct socket I need, nor can I find any information about GM possibly switching part numbers through production. It's as if the sockets I have never existed. But I need 2 of them. How do I purchase parts that don't exist? I do not want to buy used.

Just curious, did you check with our sponsor? I would be curious if Ames sell a socket or sockets that don’t work. Here is a link, last 3 on the list:

I have repaired several original taillight harnesses. Sometimes you can remove the socket wiring and metal contact end, clean, and bend so that when it is reinserted it makes contact. Not always easy but with the right tools can be done. I know you said you do not want used sockets. but again sometimes you have no choice, I am pretty sure I or other members here would have some that would be fine. Good luck.
