Frame difference--front between 72 and 73
Will a 73 frame interchange with a 72? What would need to be done to make that work? I know that the rubber bumper vs. the chrome bumper makes some difference--how much?
Thanks

I know for sure the front frame horn bolt holes. Doing it now. I heard that the body mounts were lower also to make way for rubber bushings. I know the 72's had aluminum pucks and 73 had rubber.

Body Mounts lowered slightly to accommodate thicker rubber bushings.

Per the interchange manual that I have ("I need a part for my classic Corvette" by Research Specialties) shows that the '69 to '74 frame can be used "but are not identiical." I know that the front bumper mounting horns are different. I had also heard that the metal body mounts for 72 were thinner than the rubber mounts for 73. So would have to assume that if you were to maintain the body relationship to the frame either be frame body mount would need to be changed or the mounts on the body would have to be different. Otherwise the 73 body would sit high on the frame.
