I've recently learned that while our B-bodies Power Boosters mount engine side directly to the firewall, the A-bodies have a stepped bracket in between the booster and firewall. It also has additional linkage to reduce over boosting from the booster. Too much boost is something I'm experiencing with my new Bendix Dual diaphragm 8" booster. It stops, but even with a 1-1/8" MC pedal feel is WAY too light for me. So it got me to investigating and I wanted to run this by you guys.
