Lower Control Arm Interchange?
 

I have a 1965 LeMans that needs lower ball joints and most likely bushings. I recently remembered that I have a pair of lower A arms for a 1972 Chevelle that are ready to bolt on. The advertisements I have seen for repops list the interchange as '64-'72, but I've learned to be skeptical and thought I would ask here.
Are the lower A arms on my LeMans and a '72 Chevelle interchangeable or not?

I appreciate the help. Thanks

The 64-72 A-body lower control arms interchange. There are some differences in the styles of bushings (round or oval) but there's NO functional differences in them. The UPPER control arms will NOT interchange as they are 64-67 and 68-72 specific.
