Brake Boosters getting scarce?

BillGrissom said
I put a booster and MC from a 95 Breeze on Dart stand-off brackets. Cost ~$20 at junkyard. I installed an adjustable prop valve ($28 ebay) for later front disk brakes.

Can I use this with front and rear drums just by not using the prop valve, and did you have to modify rod to hookup linkage at standoff bracket?
