I,m going to be doing the disc. brake conversion on a 66 Dart,I have all the parts for the swap.The upper control arms are off of a 73 Dart Swinger with disc brakes.Is this big ball joint??I,ve read that you need the b.b joint,I,m hoping that the ones that came on the car are the big ones,cause they look to be new.This would help with a lower cost for the swap.Any help is appreaciated.Thanks
