Hey Joe, I was wondering if this conversion could be done by using disc spindles and ball joints off of a late model car and putting them on the early model control arms. I know when I did the suspension on my 64 I drilled out the rivets that held the ball joints to the control arms and put new ball joints in with nuts and bolts. Could a control arm be modified to accept ball joints from a later model car that would have front disc?

The only problems I can think of is the difference in the length of the spindles and the steering geometry where the tie rods meet the spindles. Any ideas?
