A friend wants to install new door hinges on his 67 hardtop and he ran into something curious. The original upper door hinges are stamped steel on his 67 but he says he could only buy the cast aluminum ones that fit 62-66. He compared the steel and aluminum side by side and says the hinge pin is in a different location. I thought doors for 66 and 67 were interchangeable. I know the 67 has the door lock knob but I didn't think the door shells were different. Are the 67 hinges one year only? Will the earlier aluminum hinges work on a 67? Inquiring minds want to know.
