Buddy restoring my car found it in Dave Wises book. It show what Hamtramck and what LA used. Hamtramck is a Philip screw with a star washer, LA used a Philip screw with a head that has a molded in washer look. I don't have a picture and that's why I'm asking.

I'm doing a concours restoration on my 70 cuda 440-6 (vary early build). Previous owner owned a GM dealership and when he restored it filled the car with the wrong bolts/ screws etc..

This is the last thing I need to figure out / locate.
