Thanks a ton in advance.

If I understand you correctly, you had a vacuum booster that was in working order previously?
The way that I understand it, you need a dual master cylinder and a proportioning valve from any disc front / drum rear braking system.
I used a proportioning valve, formed steel brake lines, and mounting bracket from an Astro Van. I like it because it’s neat and compact.
