I have a 67' c-20 that im converting to disc breaks, im using the original cradle with the 5/8" studs for the upper control arm. i think the upper a- arm shaft assembly will fit the upper control arm in 1/2 ton or 3/4 ton the only change seems to be the ball joint, can the lower ball joint in 1/2 ton be installed in the 3/4 ton control arm? i have a complete 72' c-10 cradle with disc brakes that im stealing parts from. wondering if i need to use the 3/4 ton lower control arm. Any help would be very appreciated.
