Yep, as usual you guys are way ahead of me. I found a great resource in Vehicles of Victory These guys specialize in Military Chevy and GM trucks and parts...pretty cool.

I found the original seals, Napa parts numbers, 60 year old original brake cylinders, lines and hose, and much more. By this time I'm done, I'll be able to go 37 MPH! And stop too....
