There are some appearance differences in the '62-76 lower control arms however.....including the sway bar types. I can point out a few of them if that is a concern. There were at least three different rubber bumpers for them over the years too. '62-6 models had two different center links, a 6cyl version and an 8cyl one. As far as I know, the '67-72 were all the same. Then you have the '73-6 version. Swapping them out would involve changing other parts of the steering linkage and the K-member in some cases. There may be some other details I forgot, but, I'm sure someone will flame me and point that out!
