Identifying brakes

I'd like to replace pads and rotors (and maybe drums) on my '73 Duster but don't really have a place to work on it, so I need a way to ID the brakes before ordering parts and making time at a shop. They're stock parts, as far as I can tell. How many different stock set-ups are out there?

The front has BBP spindles and single-piston calipers. I think they are the "floating" type - I have some pictures I can reference from doing suspension a few years ago. The car was a /6 originally so I'm guessing the front set-up was swapped in at some point to be BBP, but maybe that came stock too?

The back has a 7-1/4" rear-end with SBP hub (and bolt pattern adapters to BBP wheels). I haven't touched those drums except to figure out that the parking brake isn't hooked up.

Rallye wheels all around, will have to double-check their size if that's important. No power brake booster on the system.

Sources - I go to rock auto, Jegs, or Summit for most things, any other recommendations for brakes specifically?
