Yeah, 600 is way too low, and that's MC and/or booster issues. Or a leak! Well, could be that the rear shoes are traveling too far before hitting the drum too, not enough sweep on the pedal/MC.

Yup, you need a new connector, Help products has them, and since you have to splice anyway, you can add a length. The aftermarket prop valves, some do have a different connector, and may stand off higher, making the original connector not fit well. Honestly, I just said effit, and left mine off.

Hm on the booster, might be the issue. There's some referb shops that do those specifically, the 2nd gens, might want to look into that, could be your problem all together. There was something wierd about the 79-81 boosters, can't recall, but if they list them for 70 1/2 - 81, might be your clue. Check PY, think they're affordable, and they're correct.

MPBrake.com has the push rod depth checker, found that earlier doing a search, never knew they had one! 20 bucks is worth it!
