Kim Steel parts are available from these folks, just shoot them an e-mail:

We have a room (Cues II, Marietta GA) that has a room full of Kim Steel's: They play just fine; some just "more fine" than others.
I recently had the opportunity to play on a new KS Mk II at an associates residence in the UK, and it was quite enjoyable.
I was on the lookout for a stateside Kim Steel before falling into an absolutely pristine, two owner (home use), 1964 9' Brunswick Sport King that already had the rails extended and pretty fresh rubber.
The folks at Sam's I traded e-mail with were very helpful, and had I located one before purchasing the Brunswick, I'm confident that anything needed could be sourced in a reasonable amount of time.
Hope this helps.
