I can use some help finding the correct master cylinder rebuild kit

[Mitchy mitch]

I have a 1973 Tx650. I am having trouble finding the correct master cylinder rebuild kit. I have looked on ebay and can only find 1977 and up kits. When i looked on Mikes the kit that is supposed to be for the 72-76 kit does not match mine. I tried looking for info on here but the posts were old and the links did not work...
Ive included a picture of my master cylinder taken apart. I would greatly appreciate a point in the right direction. Thanks

If the rubber bits are still useable, you might get lucky with a cleaning

The rubber seals are getting cracked otherwise i would reuse them. The bike sad for 30 years without getting used.. Thanks for the advice though

Did you have any luck on this? I am having the same problem.

Is this not the same one in the OP picture? When a kit is for several different models there can be extra parts you don't use.

This will work in a 73? Thanks a lot!
