It would have been easier for me to find an 8" booster from a '78 T/A, but boneyard doner cars are scarce in LA. Also, the local parts places (NAPA, PepBoys, AutoZone, Kragen) seem to be useless when it comes to older musclecars. I'm sure if I had a Honda...
Hopefully, this booster/master combo works. I've replaced EVERYTHING in the brake system, but it still feels underpowered. 16" of vacuum from the manifold; 20" from an installed vacuum pump. It should all work fine, but.... we'll see.
