Turbo Coupe rear end questions

Okay I just searched some questions I had on the turbo coupe rear ends and had a few spots I wasn't clear on.

I am probably getting a 93 Mustang Convertible here next week, and want to make it four wheel disc with the 3.73 gears so Turbo Coupe is the way to go. The car I have now is what I plan on swapping everything over from, but my rear end was very badly put together.. Crappy welds, leaks at the welds and seals cause the previous owner messed it all up.. ANYWAY, my question was that I have all my brakes from a 2001 Mustang GT, PBR's up front, and just the basic rear disc brakes. Are the 01 Gt rear calipers better than the Turbo coupe rears? And if they are, can I just use the brackets I'm using on my car and just bolt them up to the Turbo coupe rear end and all good to go, or do I need to get all different axles and everything than the sn95 axles that Jrich says to use, along with the Mazda rotors.

Just getting my list together of what all I want to get to make this car go together smootly later on..

Okay so the brackets for my rear discs should just bolt directly onto the TC rear end? I don't have to rear end yet so I can't just go and try it myself. Also i'm not sure what axles I have atm.. any way I can tell? I want to get new ones though cause mine are wore down pretty good from the bearing through the hardened part.

So basically ill be able to just take all my brake stuff off the rear end I have now and it should bolt on directly to the TC rear end? Just want to make sure I get everything I need

I am almost certain it is the original axle cause the rear disc have a bracket welded, then the caliper bracket bolts to the part he welded to the axle dude, which he did an extremely crappy job of. So I am almost certain the axle housing is the original cause it also has the 2.73 gears unless the 01 GT's came with those also.. I think all that are from the 01 are the calipers and caliper brackets.
