Anybody know what size of Torx GM uses on all there 80's cars? I am thinking #50.

Thanks
Steve

I have a 50 that I used on the door post, don't know what else it might fit.

From what I can gather most GM floor anchors, door post pins are all T50.

In some cases they have a T-500, not a typo T-500.

Basically, a slightly shaved down T-50. Smaller than a T-50, bigger than a T-45.

You may be able to tap a T-50 in the bolt head.

How about T-47... available in the auto section of the tools at Sears...

Thanks for posting that!! I was just gonna post this question since I need to take out the headliner in my Caprice and to drop it down I need to remove the shoulder harness anchor bolts.
