Front Disc Brake Conversion Confusion

Looks like Scarebird kits only fit up to 72. They show a couple different kits. I'd have to call to see what I need to do to make one work. Mopar There are two kits that come close. It's not clear, but it looks like one is for SBP and one is for BBP. Then, it still needs the MC and adjustable proportioning valve.
