1966 Disc Brake Conversion Questions

If you're not worried about the bolt pattern you can grab all the brake stuff off of an F/M/J body from the local wrecking yard. Just take the spindles on out, you get the spindles, caliper brackets, calipers, and rotors (if they're any good). The 10.87" brake set up came on F/M/J bodies all the way up to 1989. You'd still need lower ball joints for a '73-76 A body, and either '73-'76 upper control arms, or Dr. Diff's ball joint adapter sleeves. I'd guess that you could get the master cylinder and brake distribution block from the same donor.

Check your local parts houses for their core prices, sometimes its cheaper and easier to just pay the core charges for the calipers, unless you find a pair that you're willing to run as is. Around here the core charge is pretty much the same as the price at the yard, so I just buy new calipers for peace of mind. Same on the rotors, unless you find a really clean pair at the yard its easier just to buy new stuff. Then you just need the spindles, caliper brackets, and distribution block from the yard, and just source the calipers, rotors and m/c locally or online. RockAuto has pretty good prices on most of that stuff.

There are a TON of threads on this conversion. In fact, if you REALLY want to narrow things down, just search my posts for "disk brake swap". I think I've commented on threads like this at least a few dozen times... :wink:
