I have a Wilkinson Vintage trem on my K-line, basically a stamped steel Fender style trem, with the major difference being a push in arm instead of screw in. It also has a set screw. The problem is the arm makes an audible click when depressed past a certain point. I've tried pulling the arm out further and I can get it to stop, but by then the arm is only half an inch in the hole and is unusable. Anyone have any suggestions? I had the same problem with this trem on my last Suhr.
