Just installed a vacume assist out of an 88 mini-truck, front brake calipers out of a 94 fourrunner(on my 78 axles/rotors), rear calipers from a 78 malibu(on disk brake bracket, chevy half ton rotors) and a master cylinder from a 92 FJ80!
Man, can I stop in a hurry now!! Should have done this conversion a long time ago, it's almost as much of an impact as adding power steering.

Oh what a feeling!!
