Hello all! One of the many things I am doing to my 1969 patrol is upgrading the braking system, as well as a V8 swap. The V8 swap requires a larger bore clutch master cylinder than stock, and instead of paying $60 for a Wilwood, I found an "OEM-type" master cylinder that works for about $26, and has the correct mounting bolt spacing of 2.25"! I also want to use Chevy truck brakes (disc swap eventually), so I wanted a large, tandem brake master cylinder as well. I installed both cylinders at the same time and actually took pictures for once, so I figured I would share the knowledge with everyone here. First, a parts list:
BMC: 1990 Chevy C1500 truck (Cardone p/n 132352)
CMC; 1980 Jeep CJ5 or 7 (Dorman p/n CM106439)
1.5" tubing (similar to roll cage tubing, dont need very much of it)
1.5" tubing exhaust flange, 2-bolt
2.5" (I think? more detail below) exhaust tubing flange, 2-bolt
2.5" tubing (very short section)
1/4" steel flat plate (I think the piece I used was 2" x about 2.5")
Besides the master cylinders of course, I had all the materials laying around my shop. It took a few hours of figuring out what/how to do things, but it turned out great I think. If I had a more appropriately sized flange for the BMC (you'll see), it could have turned out better, but that would have been extra time and money, and I have my scrap piles of metal so I can use them, so I used what I had!
