I know prob covered but can't find with search from my phone.

Have 50 2 ton I want to swap master out for dual chamber and considering using modern booster as well.
Unsure of hydro condition and not interested in rebuilding. Gonna be a working daily driver need off the shelf napa parts for future replacement.

Assuming I can use the vette dual disc master since have drums both ends. Will use same booster as my panel which was created before kits and uses 1971? Ford 1 ton dual chamber booster 7" under floor and has insane stopping power.
Gonna be hard to find a dual master with enough bore to move 1.25" worth of fluid. Maybe early 70's big truck?

Ideas?
Part numbers?
Pics?
