When changing over to manual discs, is it necessary to change the lower control arm/ball joint? Is there any difference between the 4 lug drum lower control arm and the 5 lug manual disc lower control arm? How about tie rod ends? I have spindles from a 76 disc maverick, and my car is a 1970 with a 200-6 and puny 4 lug brakes....
The spindles will bolt up to your existing ball joints. You will probably need to swap out the outer tie rod ends. I did the swap on my 70 last year.
