Nobody list parts for anything larger than a C-30. Anyone out there have a source because I an out of places to look. This is a dual brake and clutch unit with 1 1/8 bore on the clutch and 1 3/4 on the brake side.
Thanks ahead of time for any help you can give

I'll try to find their info.

It covers your options on having cylinders sleeved and rebuilt.
I'm not a fan of brass sleeved cylinders. Stainless is longer lasting with fewer troubles, and therefore a better option.

I just read thru the old thread.
Mark "the machinist" Frappier sounds like a good choice. Up till now I never heard of him, but will keep him in mind for future needs or references.
Thanks for posting it.

UP34404, 1 1/8" brake cylinder, 1 1/8" clutch cylinder $79.49
UP19089, 1 1/4" brake cylinder, 1 1/8" clutch cylinder $214.00
I don't know why the discrepancy in price between the two, hope that helps. | | | | | Joined: Sep 2008 Posts: 10 New Guy | | New Guy Joined: Sep 2008 Posts: 10 | Finally I had some Luck at Car Quest. They had a book that listed the C-60 and another that showed the Master cyl. They said they can get it for $325. I ordered the rebuild kit for $35. Hope it works. Thanks everyone | | | | | Joined: Sep 2008 Posts: 10 New Guy | | New Guy Joined: Sep 2008 Posts: 10 | All fixed. Yeah! Car Quest | | |
