Boosters!

I have posted this many times. I pride myself on cheap and resourceful. I didn't want heavy cast-iron junk, so I put a modern booster/MC on 74 Dart brackets in my 65 Dart. Many would work. I just looked around in the JY and robbed a ~95 Breeze w/ ABS (non-ABS has different ports). All Cloud Cars should be the same. If you go newer, most have bubble flare ports (see youtube to make). My flex tubes and prop valve bracket are from an Intrepid I robbed first. Its booster is similar (spare now), but the MC has a tilted reservoir I didn't like. JY mistakes are inexpensive.

You could spend >$250 doing similar from big name places, and most people enjoy convincing themselves that makes sense. They even fault people like me, saying "safety issue, don't take chances" to assuage themselves. My brakes work fine and I can get parts cheap at any local store. That said, there is a relatively inexpensive A-body setup on ebay now, ~$140 I recall. It is based on a GM booster but w/ Mopar lever and pedal link. One guy here said he had to adapt it a bit to fit his pedal position.
