brake booster

does anyone know if there is a small brake booster that bolts up to a stock mazda master cylinder and firewall, like from a 323 or a 626 or something. any help on this subject will be greatly appriciated thanx

Chevy Sprint/ Pontiac firefly.
I have one in the garage that I used for a while. Gives a bit more clearance, and they are cheap at the wreckers.

what year mazda do you have I found out that an 86-87 mazda has a brake booster that is 2" smaller than the 88-93 and they both bolt up the same way if you don't need a lot of room this might be an option

the metro booster bolts right up dont have to redrill holes or anything later P

thanx guys
