The booster and master supplied is basically the same as Master Power's set up, toss it!......the dual diaphram is the only way to go as Brian mentioned, however the Bendix dual diaphrams only use on an E body was the offset HEMI application in 70-1,.....if looks an "originality/ correctness" in the engine compartment are required, the standard Chrysler/ Midland Ross "pancake", single diaphram booster, with a disc/ drum master with a 1" or smaller bore will produce about 1000-1200 PSI to the front lines( and approx 800 psi to the rear) if your running SSBC single piston caliper, or a stock 70-4 pin type caliper, the Bendix Dual diaphram will produce approx 1500 psi to the front, and 1000 psi to the rear,......you didn't state if this was a 2 or 4 wheel conversion, if you've done a 4 wheel SSBC conversion, eliminate(remove) the proportioning valve, run the rear line directly off the master, the front lines, substitute a brake Tee to "tee" the front lines off to both wheels, and use a MOPAR Disc/ Drum master......
if you still have the rear drums, use the correct disc/ drum master, as well as the correct disc/ drum proportioning valve
I've done the above mentioned mods to quite a few customers cars, as was as to mine, tested the systems with flow and pressure equipment thru the system, as well as individual wheel tests simutainiously.....I've logged tens of thousands of miles on the roads, as well as track time, not one faliure!.....I wouldn't recommend something I haven't performed myself
