If my memory serves me correctly you will need to brill bigger holes in the 63 cross member where the u bolts hold the lower 86 control arms on. As for the rear I would just stick with the 63 trailing arms. They work great. I would by the front end parts from a junk yard rather than buying a hole truck. I think there are a couple of threads on the forum discussing this same exact thing. Do an advanced search rather than trying to use the google search window.
