Hi there I'm new to the site. Ihave a 1967 chevelle malibu that I am currently rebuilding. I have redone the front suspension everything new but am having a problem. I took the suspension from a early model 1966 chevelle and one of the bushings are  a different size on the front lower control arm. The problem is that when I went to change the control arms one of them broke around the lower ball joint. Now i have one arm out of 66 and one out of a 67. Are the two control arms different 

No,they are the same
