I thought I'd be able to find a howto easily but I can't seem to find any. I'm putting in the new master cylinder so this would be bench bleeding.
I'm also going to have to bleed the whole but those instructions are readily available.

I replaced mine in my 81 it has the same exact setup as yours.
All you need to do is connect all of the plumbing back up and bleed it through the brake calipers until you don't see any bubbles by doing the classic tandem brake fluid flush with someone else in the car pumping the pedal.
Otherwise you can bench bleed it by reattaching the reservoir and pumping the piston a few times to get most of the air out and then install it.
But in my opinion you are wasting your time and effort trying to not get brake fluid on you paint by bench bleeding.
