When I did my conversion on my '65, years prior I had bought what I thought would be the correct master cylinder for my application. I mean it was part of a kit, so of course it was correct....pssshhhh. Then when I actually wanted to install it, I realized the MC was for disc/disc as you stated, and it was supposedly for corvette. I called them and they said it would work fine with rear drums, and to replace all the rear lines with the 1/4" lines. I didn't believe them. Why would regular disc/drum MC's have a big reservoir for the disc and a small one for the drums, and 1/4" lines for the disc and 5/16" for the drums? Or is 5/16" and 3/8"? I digress. I wanted disc/drum, so I went with a MC for an '81 C20 and the truck stops great. I didn't answer your question, or did i?...lol... Seriously, though, CPP! How do they stay in business...
