I know a guy who will let me have the front disc brakes off a 72 mustang. The setup is still on the car, including power brake booster, master cyl, and proportioning valve. He said I could have whatever I want. So, will it all fit and if so, what pieces do I need to make it fit?

The bearings in the hubs are different. YOu would need to change the spindles.  ------------------

I have 71 Mach 1 spindles and disc on a 66 convertible, its not too difficult if you do not have power steering. The outer tie rod have a larger taper than 66 so you will have to use 71-72 outers and probably will have to cut some of the threads off also. If you have power steering you will have a couple of choices, use a tapered sleeve on the 66 tie rod end or weld the hole in the drivers side spindle and have it rebored to the smaller 66 taper.Mike

It will be a bolt-in swap, using the 71 spindles. (It's most likely a D1 part #) Check with Mustang Steve for the shim for the tie rods, and they will slip right on. Use a 74 Maverick disc brake master cylinder (w/o power), as it has the right size fittings and are on the correct side, and use 67 disc hoses, as they come in form the correct angle so as to not bind. 1 thing- you won't be able to use styled steel wheels, as the hubs on the 70 + up drums are too large. Aftermarket wheels will have no problem. Everything else you need is available form the parts house- 70-73 Mustang, Granada, Monarch, Comet, & Maverick disc brakes are all the same.

kcode- did you use shims? Just wondering what they shim. Will 71 tie rods not fit without them? I have no power steering on the 66, and am using aftermarket wheels. No opinions on the power booster and master cyl, or do I just have to try it to find out? Thanks for the great info!

Kyle,
I'm not sure on what or where you are using "shims". I did place a spacer or shim under the nuts on the tie rod ends where they bolted to the spindle. The nuts would not tighten enough to pull the tapers together. For Master Cylinder I am using a manual 67 and no brake booster, no artifical sweetening. Wilwood proportioning valve to Stainless Steel rear discs also. Mike

Check Mustang Steve's site, and you will see the shims he has made. The 66 tie rods are smaller than the hole in the 70+ spindles. You can either change to the later tie rod, or drop one of these over the tie rod end, and it will take up the slack. It's actually a sleeve that fits right over the tie rod. His site also gives you a pretty good story about doing this swap. I'd suggest checking ot out, as it should make the job easier and save you time and aggravation.
