To convert my 68 barracuda front end over to disk brakes, I saw somewhere that the uca are the same on dsk or drums setup. Is this correct? can you purchase sbp disk for a conversion?
 
I've heard that the ball joints are differant. I'm going to switch over to the sbp discs too, I hope some one can give a good answer. I hope I can just use my stock uca ( Mine was a stock 10" drums)
 
Ditto,

I converted my 68 Dart from 9" drums to sbp Kelsey hayes disks without changing upper control arms or ball joints.
 
Upper control arms and ball joints are the same for disks and 10" drums (9" too I think) pre-1973. Problem is the Kelsey-Hayes parts are getting rare and expensive. You need spindles, lower ball joints, calipers, rotors, and dust shields. The latter is hardest, though not essential. On the upside, rotors used to be hard, but are currently cheap from Centric. I got 2 for ~$26 ea as a plan to try a roll-my-own disk setup, if I don't go K-H. Also, Mustang's used a similar setup so some parts interchange I recall.

For not much more, you can get the Wilwood conversion, which has light aluminum calipers and works with your existing spindles and ball joints. The most affordable is Scarebird's, though only for 9" drum spindles I recall.
 
UCA and ball joints are the same on the 72 and earlier. I have not seen any "new" SBP disc brake set ups. If you go to salvage, be sure to get the proportioning valve and master cylinder, too.

The disk brake road wheels are different from the drum brake ones. The disk brake wheel had a ring on the back side which held the wheel flat against the "hat". I've used drum brake SBP wheels on disk brakes without an issue. I've made sure the wheel is squared on the hub and that the torque on the bolts is equal. I also did not do any serious canyon carving with it either.
