I need to install brake lines, MC, and prop. valve. Help!

I have a 71' Duster that was originally had a /6 and 4 wheel drums. It now has a 318, 73' discs in front and a Ford 8.8 in the rear with discs. I now need to run all new brake lines, install a new master cylinder (since the original one is not power assisted) and install a proportion valve. Any help on size of brake line, which master cylinder to install, and which prop. valve to purchase would be great!

I would assume I want power brakes, right?

I want all new line since I'm sure the old lines are not in great condition.
