My question comes from here:
Exactly what is this modification that is required? I'd like to know just for curiosity.
Ball joint is wider where it attaches to the spindle.
The ball joint "stud" is bigger than the rest of the Foxes, thus the hole in the spindle is larger.
There is available (or at least used to be) an adapter sleeve that goes over the Fox balljoint to allow you to use the SVO/Lincoln spindles. I used them WAY back when on the old black '83 we had when I converted it to the 11" stuff (had the spindles left over from my SVO-suspended Capri).
Thanks guys! ;)
