Took a quick look at the rear drums tonight. Disconnected the parking brake under the car and confirmed that the levers were all the way loose on the rear brakes. Confirmed that shoes are fully seated. Still does not fit.

My neighbor helpfully found a drum/shoe measuring tool and I checked using that. The inside diameter of the drums measured out at exactly 12". The other side of the tool checks the shoes, and they measured out about 1/16" too wide with no adjusting room. So it looks like I'm going to have to make some phone calls to see if anyone can grind the pads down.

I took a closer look at the master cylinder. It's a Wagner Lockheed FD 5031. I can't find any info for it online, but it looks almost identical to this one.

Besides being dirty, it "appears" to be in okay condition. No leaking that I can see.

There is a rat's nest of brake line, all leading to a junction box/proportioning valve. See the picture for reference on the lines:
1.) Master cylinder line 1 (in)
2.) Driver's front wheel (out)
3.) Passenger front wheel (out)
4.) Master cylinder line 2 (in)
5.) Rear (out)

I don't love it, but I'm out of time. My neighbor needs his shop back soon. So I'm going to get the rear's wrapped up, flush and bleed the whole brake system, mount the new tires when they get here and move the car out. After some brake testing I hope to get the car on the road to do some controlled testing of brakes, engine, transmission, cooling system.

Eventually I'm going to go back to the original BTV brake system and get the whole thing back to original. Man, I knew these brakes were going to be a hassle....yuck. But at least I'm learning.
