MoPar Brake Upgrade Options?

If you pick up a copy of my B body book (available on Amazon) you'll find a bunch of custom brake stuff. I think I did about 3 chapters worth of brake stuff in that book. Almost all of it applies to A body cars since most of the front end stuff interchanges between A, B and E body cars.

Ok cool. I'll look for that book and I'll put FMJ cars on my wrecking yard watch list for the spindles, but everytime I find a '73 up Mopar with disc brakes, it seems that's always the first to get salvaged.
