Power brakes booster question.

Make sure the booster will clear your valve cover.... Example being, The booster Oreilly sells for the /6 Duster will not fit the V8s, it hits the driver's side valve cover. You need a booster that is around 7-8 inches in diameter. I believe I picked up a replacement for my 76 Duster that was designed for a seventies model Fury. I think Oreilly had it classified under Plymouth Full Size Sedan. It was a pain to track it down. I think they ordered three wrong ones until I finally found a parts guy who had a clue how to use their computer system.

Ive read that a guy used the booster and master cylinder from a early 90's Horizon or something... It was either on a cuda or Duster. The bolt holes match up with the Dusters.
