I've had a few low-end import guitars with "fake kahlers" on them... I have a few sets of the lock-nut screws and stuff. PM me w/your address and I'll send you a set of lock nuts and pads to try out. THey may or may not fit, but I don't need them for anything anymore so if you want 'em, lemme know.
Oh yeah the last guitar I had with the crummy trem, I took it out and got a "real" Kahler, they sell brass plates that cover whatever rout your guitar has, and the Kahler attatches to the plate. In case you don't want to mess with plugging the old one, and re-drilling the new one.
