Master cylinder options?

[OilHammer]

My clutch master let go and I need to rebuild it. The lining is just fine, it's really just in need of new rubber parts, but the trick is 04471-35014 has been discontinued. Pretty sure my 66 fj45 is running a 1" bore size, but I would need to tear it down to confirm that.

Given pretty much everything OEM is gone, what are my options? I hate to "update" an original truck, and I would think a 1" cup and gasket are pretty common parts. Anybody know of a chevrolet part that crosses or something similar? IIRC, I found some generic wheel cylinder cups that worked great on the brakes, so gotta be a clutch similar situation.

I could not get my 67 master open to even try to replace parts. Had to replace it the line and the slave because they were 9mm flare parts that you cannot find anymore.

You can still buy that kit 04471-35014 not genuine in Australia. I got this one 3 months agao about $40. You might try a PBR one PN K7313

Thanks Kurt!
I found a replacement master at RockAuto that just arrived yesterday. Looks to be the old school casting, so I should be good to go. I actually pulled my old master apart and realized that it wasn't the new one, it was the brake master. So I actually had some pitting in there that was causing the leak, and it wasn't just a faulty seal. Good to know you have the rebuild, as I might send the original out for sleeving someday. I still have the old tuna cans that I want to put back on at some point.
