58 Viking brakes
 

I have a 1958 Viking with the original frame mounted drum drakes with single master cylinder and remote hydro-vac brake booster. It’s tough and expensive to find and buy parts to keep it original. I don’t know the difference between boosters, but it doesn’t seem different.
Can I use a newer frame mounted power brake booster and dual master and keep it drums?

If you replace the master and booster you want to be sure it has enough volume to handle the large brake system, that's about as much as I know on that subject. Rock auto has a return and rebuild service for the booster, part number is 518028. It costs $237.79 plus freight when I looked today. They have the master cylinder, part number is 35571008 and it's $90.79.
