I have not had a chance to dig my notes out and look. I apologize. (I am reading/writing this while attending a phone meeting at work!) If I remember correctly, the RAM website has the installation instructions that you can print. I will do my best to get something tonight. If it is leaking, my guess is your travel on the clutch pedal is greater than the travel on the RB. It causes it to force fluid pass the o rings. As Andrew said, remove and rebuild (kits are cheap $13 or less) How ever, unless someone has a trick to install an o ring on an INTERNAL undercut, your best bet is to send it back to RAM and have them repair it. Ask me how I know.
