jcw- thanks for reponding. I was thinking that the CMP might be the same, but the CMP is a little larger (not by much). From what I've read and seen on the H9, get rid of the plastic clevis and get a metal one. Also, talking with a friend of mine that has the H9, go with 4-40 rod for the retracts. That's what I plan to do. I'm planning on an OS 70 4S, so we'll see what happens. Just waiting for it to arrive.
