I am rebuilding my roco as a lay-off project. It's a good experiment and I'm having fun. I replaced the bottom out bumper and got it back on the bike and am really happy with how it rides (nice supportive HSC and fast rebound, some progression from the ifp). Unfortunately it's making a clicking sound on short hard hits, sounds like this may be from a worn out o-ring on the HSCV assembly. I've removed it and did my best to measure it, but I'm wondering if anybody has the specifications available. Seal kits are currently only available from a guy in Israel.

I measured about 28mm ID and an o-ring diameter of 1.76mm. I'm guessing this should be 2mm? Any good place to buy a replacement- like a FLAPS or home depot? Easiest would be to find a similar in hand rather than ordering but I'm not sure where.
