Flech - you might be right. I got hold of Abu - finally, and they told me the part was on backorder till Sept. This is after I ordered the part in March and have been told it would be available "soon".
I have several Revo's and some of the older C5's but if Abu is unable or unwilling to make parts then I will be going with Shimano from now on, I don't remember reading about people having this same chronic parts problem I do.
Thanks for the PM Wayne, I will check them out.
