I should be able to look them up in my Cdn Pontiac & Chevy parts books. When I went to replace the drivers side hinges on the 70 454 Laurentian (2 dr hdtp) I found they were the same as a 4 dr sedan, so I grabbed a pair from a junk yard. I ended up not using them (as my door guy had another set), so they're kicking around but in need of a rebuild.
I'll let you know what the parts books say. I suspect the findings will be the same as 1970, just curious if a convertible needs something special.
I doubt convertible is special... door jambs are cut (factory) for power window harnesses but that shouldn't affect the hinge... let me know what you find and I'll check too!
when you mention hinges, im forced to change the pins in both the 75 and the Camaro, I suspect most two doors have this issue, with the bushings being worn out, crapy tire has them, its a good investment if you have them out any way.
I wound up grabbing a set of four from eBay for about $250 new. Hope they're well made. I might regret not getting OEM units and re-pinning them, but we shall see!
leave the doors closed and do the Duke boys method (especially easy on a ragtop), those chinese hinges won't wear out if you don't abuse them (by opening and closing the doors).
