WTF Caddy rear brakes?

OK, new drums, springs, shoes, wheel cyl, brake cables, master cylinder.
I've done this job on caddys half a dozen times before.
This 82, fresh install, power bled, went to adjust the parking brake and had to run the adjuster ALL the way down on the cables.
And the pedal is lower than it ought to be.
I pulled the drums, the auto adjuster was half was and working, I manually snugged them up, slightly better but the e-brake is
nowhere near it's normal behavior. Can you put rabbit shoes on a caddy by mistake even? I don't think so, the part number on the box was right.
The rabbit brake cables are shorter and would have the opposite problem, no? They fit like I remembered they should.
Thoughts?

Well after sitting here and drinking half the night, I've decided the shoes have to be bad somehow. They are Meyle brand, and there stuff is hit or miss.
The drums are chinese too, but I can't for the life of me believe even the chinese can't machine a damn hunk of metal that wrong, both of them,
and it's from a company with TUV certs, and they really look pretty nice. I'm going to go try and buy any set of 200mm rear shoes I can get hold of tomorrow,
and if I can't I'll order a set of Febi's like I've used the last few times. This is stupid and I want to drive my truck.
On and the master cylinder from O'Rieleys, while not $150 like the ATE one, the grommets for the reservoir are kinda ill fitting, only complaint so far.

Nah I tossed em like a dummy, quick glance they looked right, fit right, but there isn't a lot of room for error in there, the wear limit on the drums is 1mm for instance.

usually because there is a front one and a back one.

The back one is always the arm for the emergency brake.

No, look close. They should be mirror images of each other, left and right. They are cast differently.

Well the back shoes only fit on one side and I think the front shoes can interchange.

Yeah but the metal shoe backing is cast differently. I haven't taken measurements on them to compare yet, but look where the cross bar for the adjusters fits in. The slots are different. Different where same should be worries me.

Yes it does, but they should be pretty much mirror images left and right, or should be.
Also, just noticed my new master cylinder, the reservoir does not fit in the damn gromets, it wiggles up and down. And leaks. Sigh.

Still scratching my head on this.
Both sets of shoes are about the same contour and such. Also of note the autozone shoes have the wrong e-brake arm on them, I've seen that problem before.
But they are of the same basic dems as the set I have on there.
I shimmed the wear points on the cross bar for the hell of it, there was some improvement but the adjusting wedge STILL drops half it's travel on the first application of the brakes, and the parking brake STILL requires ALL of the adjusting thread to get the brake to work. The drums measure out at 199.75mm ID, the shoes look to be right unless both sets are wrong, the cross bar does not seem to be worn THAT much, the backing plate looks to be correct, I see no wear on the lower pivot, I can't see how the wheel cylinder would effect the at rest position or the e-brake, the cables are new Coife pickup cables. I'm about stumped. I think I can shim the upper bar, and the lower pivot, and get them to a useable state, but I really really don't dig that idea.
If anyone had a new caddy parking brake cable they'd be willing to measure, and/or a drum brake pulled apart handy they could measure a few things for me I'd appreciate it.
Something is wonky...
