finally got behind the wheel to bleed brakes, hit a snag with the rears Options

[Type 47]

It was super cool to get behind the wheel, even though I'm sitting on a 6x6 piece of wood.

so bleeding the master and front went OK; we got nothing on the backs.

I suspect the brake pressure regulator needs to be wacked or something.

Please advise before I do something stupid.

Some videos show a different BPR, this is a 75'

I would get a GOOD flare nut wrench and try to bleed at the line going IN to the regulator, then once the air is done "popping" at that location, pick an outlet line and try it there...then if all goes well move to the caliper. If at some point you are not succesful, then your restriction is between that point and the last one that you were able to bleed.

Have a water hose ready to rinse off whatever brake fluid spills on painted surfaces

OK, thanks. We'll get on that on Monday.
