Has anyone put the disc brake set-up from a '68 Mustang to a '66 Mustang? I've heard this will work but that I will have problems with the lower ball joints and controll arms? If you know about this please help. What do I need to get this done? Can some type bushing be used on the '66 lower ball joint so that the '68 spindle will fit and I won't have to change controll arms and ball joints? Thanks for your help guys!
