hmmmmmm, so if I got an original 1968 Firebird disc brake booster, (or have my drum brake booster rebuilt and recoated) and I got an original 1968 Firebird disc brake master cylinder (instead of chevy) I should be ok, right? thanks for all the great info
ps- to Mike- both my boosters are 11",which is stock, but keep in mind that the edge of the 11" booster comes within about a hair's width of your 400 valve covers. Not a big problem, just makes it hard to work on.
