I have a 1975 D-700 that needs both rear wheel cylinders replaced and am having trouble finding the part number, it takes 2 per side. If I can't find the wheel cylinders, I will probably just rebuild my old ones

I did see this number that was sold in pairs pop up a couple times EW771206

Usually easiest just to get the diameter and rebuild them.

Yes, have done that before. They have 1 5/8" piston and was hoping I could just find the number because the parts stores can't even get me one. WC24489 looks like it might be it

The WC24489 was the exact part, $25.99 each at O'reilly's w/no core. Looks like chiivy, phord and intersmashible use the same wheel cylinder since they probably use the same two speed rear axle.
