Re: 64 GMC Axle swap questions.

However, I'm starting to pull my hair out over said brakes.

I have this style master cylinder, and want to go with a dual diaphragm brake booster from Tuff Stuff.

I'd like to run an adjustable proportioning valve, and am starting to go crazy trying to find things that will make all of this work (based on brake line sizes).

Looking for suggestions on prop valves, distribution blocks, or even different master cylinders and boosters that will work.

I'd like to stick with a dual diaphragm booster though, because I'm using a Captain Fab bracket for a trans swap, and the spacing between the brake booster and clutch master seems tight.

Thanks for any input!
The booster that I got was for a square body C/K 30. The clutch master is a tight fit but it does fit there. I think the booster is a single diaphragm.
