1965 C30 SRW Rear Brakes

[ncoonen]

I have come up with nothing useful searching the interwebz for new shoes and wheel cylinders for the rear of my 1965 C30 single rear wheel truck. It has 13" x 2.5" drums in the back. The only thing I find in parts listings like Rock Auto are for 14" drums (example: Raybestos 60PG).

I think I can save the drums with a quick turn on a drum lathe but the shoes are shot and at least one of the wheels cylinders has seized.

Any clues or sources to check? Lots of later Chevy 1 ton trucks used 13 x 2.5 rear drums but I am not smart enough to know if any of these might work.

Thanks all...ned.
