i'm trying to remember what mine is
i think Right Stuff?
i bought the chrome i think 10"
it's not the dual one, and there is PLENTY of room for my fat hands and tall moroso valve covers
there was a smaller OEM size one, but my original one was the monster size and it was always a pain


not sure what your budget is, but maybe a good time to look at the hydro booster setup as well

since i run a somewhat radical cam with low vaccum, i use a CVR pump
no problems so far

To clear hi-ports with Morrosso valve covers and 1/2" spacer I changed to the dual booster from a 80 f/b, got it from Rock Auto.

That would be a 9" dual diaphram. They are great units, I have one on my 68.

This may be the same thing but im using a booster for a 4 wheel disk brake 79 t/a. Got it from advance auto. Its a little stronger than the '78 booster but i like it. I understand that if dont want the extra boost you can drill a new hole in the brake pedal lever to attach the booster rod to in order to reduce brake pedal leverage.

Does it bolt right up or are there any modifications required?
