I used 93 jeep rotors. You don't need a measurement to place the caliper bracket. Just bolt on the rotors put the pads in the calipers and bolt them to the brackets. Install them over the rotor and it helps if you have someone hold the brake pedal one you have them where you want them, this will square them up to the rotor. Then just tack the brackets on, remove everything and weld them up. Here's some pics from mine.
I used the front rotors from a 2000 Grand Cherokee, Speedway brackets, Autozone calipers and pads. I drilled the rotors for 5/8" studs, mocked it up on the axle, and put shop air to the calipers to hold them in place while welding. My rear lines are flex lines that were also purchased along with the fittings from Speedway.

I also didn't see the need for a parking brake on mine. As for the proportioning valve, I went with an adjustable one. There are a bunch of brands and styles out there in a variety of prices. Check out the ones speedway has while you are ordering up the brackets, lines, fittings, caliper bolts, clips, etc.... saves on shipping too!
Randy
thanks for the info. i have used the adjustable one before on my 65 but that was with wildwood brakes front and back. so did you just plug the rear break line coming off the factory valve and run a new line from the master cylinder etc? Mopar65 
Yep, I plumbed the adjustable prop valve into the rear line coming from the master cylinder. For the lines I used the braided flex lines that Speedway sells. I didn't use banjo bolt type lines. They sell a fitting that adapts a flex line to the banjo thread size (can't remember the size off the top of my head though).

Jeff I used rotors from a Jeep Grand Cherokee with GM metric calipers and brakes from any circle track shop for the rear.
Sorry to bring up a old post, but Jesse, what is the difference in the brake pads from circle track, compared to a regular set of pads?

That wasn't his point. The lower-cost circle track classes use a "metric GM" caliper. It may even be a requirement in some classes. Anyway, circle track stores should have them and pads out on the shelves so it's easy to just walk in and buy a pair. You don't need to wrestle with the parts guy's computer like you would at Autozone.
R.
Jesse, is/was a parts counter guy, that is why I asked. If a simple set from the local parts store is the same for $13 I'll just pick them up, and run a spacer from Speedway.
