66 Dart GT HT Whatsitgonnabe?

Not sure how far these come apart. Only other ones i have ever taken apart were GM late model mid 80s ones, and this was mostly to shorten the brake pedal pushrods, and thread them for heim joints for custom applications. Everything had to come apart just to get to the snap ring inside the booster that released the pushrod. The big question is where do the rebuilders get their replacement parts for these? I'd love to buy a diaphragm and seal kit instead of inspecting everything, trying to soften the rubber with silicone protectant, and reusing.

The metal surfaces inside the booster canister on mine i plan on spraying a couple thin coats of akzo noble S55-90 fluid resistant epoxy aircraft primer, after i dip and strip all the corrosion off everything. I may get the outside done with the gold tone zinc dichromate as original, but am also seriously concidering a gloss black for the booster as well, but only because i think that color will pop better against 1967 plymouth yellow.

I am using a larger bore 79 chrysler cordoba master cylinder, as well as the larger 11.75 inch 79 cordoba rotors, 2.75" piston calipers, and cordoba 10" x 2.50" kelsey hayes finned drums on the rear. All this was designed originally to stop a 3,975 pound car, my cuda is only 2,900 lbs. Should work well.
