On the rear, it is my understanding that you pretty much want to grab the entire rear trailing arm as well. +1 on grabbing the prop valve, drum brakes need more pressure to operate, if you don't grab it, you will be prone to locking up the rears under hard braking. Also, I think your rear lower control arms are longer than his, you don't need those.
If you have a bad front caliper, get the front brakes off his car, again, get as much of the suspension as you can, at the very least, get it from the cast knuckle out. While your at it, see if you can get the booster and M/C too.
Edit: Is this for the same car that you, prior to making this thread, blew the motor up on and prior to that were talking about trying to do a $600 performance rebuild/overhaul on?
