I saw this swap on the Monte boards , my concerns are will it clear the power steering pump reservoir and the valve coverB-Body Dual Diaphram Brake Booster Upgrade - MonteCarloSS.com Message Board

There's no way it will hit the ps pump reservoir. I don't know about the valve covers, but I question whether there's an advantage to use this B-body booster over a G-body dual diaphram booster. Let us know how you make out.

just to give an update the 12" dual booster from a caprice does fit perfect , now i don't have to pray when i hit the pedal!

I saw the same thread and installed the same booster and fits. I recommend hose clamps on Vacuum lines because i was praying when I did a blast and boost pressure blew it off at 80 or so.

how's the pedal feel?

How is the "stoppage" ?

You beat me to it.... I was going to mention the same thing.

Looks tight to me.

in my application i wanted the largest diameter that would fit thinking it came from a heavier car therefore it would have greater stopping power in a lighter car. It may only have more vacuum capacity. I also had the booster modified to low effort because factory brakes require about 20 foot-pounds of pressure to operate and the low-effort mods reduces the required pressure to 11 foot-pounds. I am wheelchair bound hence my screen name (quadzila) and require hand controls to drive the car. I now can more effectively power brake the car to build boost. I now apply about 1/2 the effort to stop the car.
