79 rear master cylinder rebuild kit

Could someone please direct me to a place where I can buy a rear master cylinder rebuild kit for a 1979 KZ 1300 mine is leaking I'm assuming I need a rebuild kit I can find the front but I cannot find the rear or are there any other models that take the same rebuild kit

im not sure what part of the planet you are in, must be a secret.
but if you are in the UK then this kit on Ebay 401113451263 has the same size rubbers as the rear master cylinder
just swap the rubbers as long as the body is clean internally.

I'm in the United States! Thanks I'll check those out. I have a leak at the rear master cylinder. Figured I'd just rebuild it. I'll start with the new rubber. Thanks again

Hi, here is mine just rebuilt by Pastparts to an absolutely first class standard for £125 .

Sorry, just realised you said master, my rear master was rebuilt by them for about the same price. Basically they machine out the bores, sleeve them in stainless steel and then rebuild them with modern seal kits and a complete visual overhaul into the bargain.
