Re: Power Disc Brake Master Cylinder Help

Interesting.. I thought I had read that the pushrods were different lengths and not compatible. My original plan was to use 71-72 disk master/prop valve until I read that the stuff is different. Can anyone help to confirm?

Good point on the prop valve being common, I guess what I'd be looking to buy is a master/prop valve combo that will go straight to this booster (assuming the master is different; I have found plenty of MC/PV that are intended for c10's).

I don't have a donor, the brake components are all new CPP parts.
