Not sure what you mean exactly by mount up. My plans was to make a mounting adapter and weld it to the axle then bolt the cailpers to it. Just not sure of all the dimensions of everything etc. But having breaks for a car that has at least 1000lbs on a runner would be nice.

I just meant the mount point on the caliper as in comparision to how the chevy calipers mount up to the bracket. I could make an adapter, but I'd rather not.

Why not use Toyota parts? 
I imagine price and availability...you buy FJ80 parts and they are going to be expensive, anything that says "Landcruiser" on it will be, compared to a GM metric caliper that is used on a bazillion of vehicles post 1995.
The brackets are custom on my kit. The AP kit is top notch and I highly recommend it.
I got pics on my website of my install.

There's only two kits that use Toyota parts. Big Rocks 4x4 (I think that's the name) which uses solid axle front roters mounted behind the axle flange (not my favorite mounting model) and FRORF's Full Floater kit.

I would suggest searching out "rear discs" on the Toyota forum on Pirate or looking in the Toyota FAQ...there is TONS of information on this subject there w/o rehashing it here...if you are serious. I hope that helps.

Yes you can use exisiting 79-85 soild axle front rotors and calipers on the back.
Big rocks offroad sells the kit to do this: http://bigrocksoffroad.com/Brake%20Upgrades.htm
$285 not too bad
Basically all you need is the calipers which if you are doing SAS and upgrading the front brakes to fj80 rotors and ifs calipers you have them left over.
Here's the how to on it too:

I was looking on pirate and some guy from the netherlands did a brake swap using fj80 non floater rotors, then made his own brackets doesn't seem too hard.

that bigrocks kit means its still a PITA to change a rear axle.
with the GM based kits, all you have to do is remove the caliper, pull the rotor off, undo 4 nuts and remove the axle shaft/bearing assembly. put in new axle shaft and bearing assembly, replace the rotor, bolt caliper back on.
with the bigrocks kit, you have to remove the caliper, undo 4 nuts to remove the caliper bracket, remove 4 nuts to remove axle shaft and bearing assembly, press off the bearing assembly, press out wheel studs to remove the rotor, put rotor on new axle shaft, press in the wheel studs, press on the bearing assembly, put in new axle shaft and bearing, replace 4 nuts to hold bearing in place, put on bracket, replace 4 nuts, bolt on caliper.
besides, a GM based brake setup can be done for much cheaper.
