Glad,I found this thread its similar to what i'm doing with my 1950 Plymouth deluxe,I also am currently working on my floor pans and rockers on my own Big Block Plymouth custom project,So i cut the old patch work of a floor out of my car and i was looking my old nasty non powered brake master cylinder and decided i was going to replace it and upgrade the brakes in general to a power disc\drum set up preferably with a brake booster (ill need to stop with the big block) so when i was shopping around i seen whats sold as an old ford frame mounted booster and corvette styled master cylinder,with the same shaped brake pedal as my Plymouth,So has anyone installed one of these on their Mopar? do you think i will have clearance issues? I wonder with the width of the frame combined with the offset the booster will add that it may move my brake pedal too far to the right. i wanna keep it on the frame there isnt alotta room to move it up in the engine bay and this looked like a cool upgrade
