Oddball car - swap to disc - ideas?

There is a way to take advantage of the rear, Put the biggest tires in there that will fit, throw the P-valve away and start swappin in rear W/Cs til you get some action back there.
You'll know when it's right by the way it stops; AWEsome.
It's like; finally getting the electric trailer-brake sensitivity adjusted right.
It's like; the car is gluing itself to the road while simultaneously trying to pitch me through the windshield.
It's like;who knew this was even possible
It's like; remember the 454Corvettes of the early/mid seventies. They had brakes!
