Need a wheel cylinder cross referance

Finally got to checking out the back brakes on the 5000. And it looks like I'm going to need new wheel cylinders.

Does anyone have any numbers or a cross for these? As usual, coming from my '61 GMC. My closest guess would be these- http://www.powerbrake-drivetrain.com

Unfortunately I don't have any numbers off them. The truck has to make it to a ATHS show tomorrow so I didn't want to start disassembling too much. They're pretty good size....

Any help is appreciated.

Here are Parts Book pages for Chevrolet, presumably the same for GMC -

Dorman W26172 Upper and Lower, 15" x 7" brakes, 1.75" bore, 1960 to 1985 GM trucks

Looks about the same as the ones on your truck judging by the dust boots and shoe pins.
