Hi everyone!!! I am about to replace the door glass on my 1950 Chev 1/2 ton. What size is the clutch head screws that are in the rail that the regulator rolls in? I need to purchase the screwdriver and don’t know what size they are. I tried to grind an old flat head screwdriver to fit, but it didn’t quite work and I really don’t want to strip the heads. Thanks for any replies given, Darcy
