Jason you should be able to use the late '60's
to early '70's(68-72) and without too much plumbing problem.There are later systems too,but might require more work to use. Buy all of the salvage yard system you can including booster,master cylinder and proportioning valve,but make sure you are buying for drums only system unless you are going to change to disc, then buy a disc setup. The master cylinder bore is different between the two systems,smaller on the drums, and it is important so you don't have too much pressure on the wheel cylinders.Make sure you have good vacuum for the booster to work,MPBrakes recommends 18 inches I think.And as Twisted6 said
get an adjustable brake pedal rod.Good Luck.
