Thanks for the ideas. Still no luck on finding a kit or replacement. Will Samples said he has a few rebuild kits available and will do it for $1,100. That's too much for this car, which I hope to turn into a daily driver.

I am about to try and fit in a random hydravac unit but I can't figure out how to pick the right one. NAPA has rebuilt boosters. They have selections for inlet and outlet ports for brida invertida, 1/2, 1/4, and such. How do I make this selection?

Thanks again,
David
