If you want a stock setup you can't beat The Right Stuff kits comes with everything you need.

They also have a non power brake kit

I used inline tube. Worked for me on my 1st Generation but I talked to a very capable guy last week that had issues on a 2nd Generation.

We used Classic Industries kit (4 wheels), upgraded to slotted rotors, but didn't upgrade the calipers or anything. The brakes work great! Especially noticeable since I get to compare them side by side with my unrestored 69 H.O. Bird that has 4 wheel drums. There's simply no comparison. I imagine the more expensive, larger rotor multiple piston kits are even better, but our basic kit suits our needs just fine.

Install was really easy, no problems with fitment or anything.

+1 on the right stuff kit.......I used it and it was very easy to install.

I originally was going to keep my 14" wheels but I upgraded to 15"...the kit I bought will work for either.

I only did the front conversion.

Here's the link for the one I used.

+ 2 on the right stuff kit...... they have good products. I didnt use the conversion kit as I already had disk brakes, but the kit contains everything required for the swap and everything is identical to the items they sell for replacement parts for existing disk brakes which is what I did. I replaced my whole existing disk brakes with their parts.

I ordered a rebranded right stuff kit today. Was $30 cheaper than summit but had identical pictures and items included. Will see how it looks when I get it.

I used "the right stuff" rear wheel drum to disc conversion kit on my '71 T/A. I added a proportioning valve to the rear brake line since I kept the stock front disc/rear drum master cylinder. Had to get a different length E-brake cable than what came in the kit, but the folks at "the right stuff" took care of that with no hassle. The rotors and calipers fit great, bleeding them was no problem, and after adjusting the proportioning valve they work very well.

Do the drum disc conversions fit behind 14" rims?

Tom, I think some of them will but the kit we got would not fit 14". You'll need to check carefully before you order.

That was the big selling point on the Wilwood kit. They clearly state they will fit 14" wheels. I don't plan on keeping the 14" wheels forever but I'm on a budget and the tires are new. I hear good things about the Right Stuff Kit but I've heard its odd ball parts from different car manufacturers.

Not true they are the stock replacement parts that if I went down to the local parts store and ordered a rotor or caliper it will fit right on .

If you can find the 14" wheels with the right wheel code for disk brakes JC or JH i think .

Here is a good chart for the wheel sizing

OK thanks, I also found a hot rod magazine article said 88-97 f body aluminum rear disc brakes are direct bolt on for 64 up. Gm rears including Gen 1-2 f body, u just adapt the hose to metric

I was mistaken slightly. The info I read from another forum was that was talking about their Signature Series using calipers from Mustang Cobras. Knowing this I may look back at the Right Stuff Kit And do the front and rear. As long as I can still run my 14's

I bought a kit from Summit, I think an SSBC kit - about $625 complete. I ended up getting a 2" drop kit because I could not find an entire kit with stock height spindles and didn't want to buy everything individually. I also needed to buy steering knuckles because they were not included. Really not to bad. I did the whole control arm swap at the same time, converting to tubular arms. The springs were a bit challenging, but not too bad.

Good luck

I did the SSBC kit with their largest rotor (13"). i have 19 in wheels so i won't have clearance issues. I did the SSBC aluminum calipers to replace my front stock calipers. my mechanic had to modify the SSBC master cylinders push-rod, but he did say this was no big deal. I used the inline tube brake line kit and fits perfect. The downside is SSBC took 3 1/2 months to get me my kit. I was quoted 6-8 weeks. but everything fits perfectly and works awesome.....I had to buy new bearings for the rotors and new grease caps
