Smaller Brake boosters

So, I'll put this here as the most use for smaller brake boosters is to do with tubbing I suppose.
The geo metro wasn't sold down here... but the suzuki swift was and the ford fiesta. These seem to be the smaller boosters that people are using. Anyone have more to add or any info/specs on them? I'll be needing to reduce the size of mine as the new manifold will foul on the standard one

1978-80 Mazda GLC brake booster. Its decent amount smaller and bolts right to the B series trucks.

Thanks Dave, I'll check that out!
"bolts right up", 3 little words that make any man happy.

Sweet, as know as the 323 over here and also the Ford Badged "Laser" (of which the 4 door 4th gen 1.3L was my first car )
Plenty about, now to find a nice booster
