GMC and Chevy TF doors slightly different - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was cleaning out the threads on my door hinge nuts last night. They are 3/8-20. The screws that hold on the panel over the window regulator and door latch accuator are phillips head. Door internal screws were clutch heads.

Thanks for all the great responses. I am out of town so I can't post pics. It sounds like a year thing and not a brand thing or it could also be that Chevy and gmc may have been made in different plants which could lead to slightly different processes. On my original 59 doors the screws were just like the ones classic parts sells (big like a 20 shaft size as previously mentioned.) On this door they are much thinner like a 10 or 12 shaft size. I will post pics when I get home.

No need to put them back in, I replaced them with regular hex head bolts.
