Looking for the valve piece that fits at the bottom of the par chamber (is that the right description?).

Looks like this:

Broke mine. My fork works great - well, it did anyhow. Called Marz - they claimed not to sell those anymore, tried to hook me up with a crash replacement deal on a new 66 ti fork, which was cool, but I don't need a whole new fork.

Are there compatible parts from other forks - like a 55, or a newer 66 (unlikely, I know, but have to ask).

If anybody has a broken 66, I'd buy this part from you...
