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" ?

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.
