brake booster swap

Anyone know if there is a smaller diameter brake booster i could swap my factory OBS with? I really dont wanna go with the hyrabooster set up less i have to.

i bought a 7" chrome one and MS for my truck, just had to cut the push rod off the old one and weld to the new rod so i'd have the same length and ends for the pedal....

pics?

I used a Geo Metro booster on my right hand drive converted s10. I believe it is 6"3/4

Not sure that wouldnt stop a tahoe well. And im sure that it didnt just bolt right up huh?

The Metro booster is stronger than my stock booster. The size makes no difference, and actually if I had not changed my steering it would have been pretty close to just bolting up, by the way I don't know to many just bolt on things

7 inch hot rod booster, factory MS. Thats what im running on my SFBD 04 GMC Fullsize.

Where did you pic up that 7" hot rod booster?

is this what you guys are using?
