SBP Disc Brake Setup

Not to be the bearer of bad news but I am pretty sure 1973 and newer are different than their earlier sisters. I have heard rumors that they will work if you change the upper control arms but I am unsure (maybe some of you other guys can confirm it). I have a spindle and brake set from an 81 F-body. My interchange says they fit the 73 and up A-bodies. I have to check, but I think it is BBP. I have a prop valve from a 74 Charger that will work but I don't have a master and/or power booster. Earlier booster and masters should work though. Please PM me for more info.
