Ok. Desicion made.

McGaughys Big Brake kits. Both front and rear. Hotchkis springs.. now my question is the master cylinder and proportioning valve. I have a CPP booster I bought for my Big Block truck. It is too big. (OE style) I thought I would use it on my GMC (smallblock, short valve covers, etc.) Make sense. .

My question - Do I need a specific Disc / Disc master cylinder? I know the prop valve is disc/disc .. and what size lines would I need from the MC to the valve? I might just buy the kit with the smaller booster style and kinda swap boosters from the new kit to my BB truck .. would that work? that gives me a smaller booster to fit around the taller valve covers.

thoughts? I'm going to order it tonight. The McGaughys kit is cheaper and that's what's on my 68 too. It went on great. I'm going this route. I can do big brakes front and rear for the same money I could do just the front from CPP.
