Ok, THANK YOU very much for the info, it will come in handy, but right now I got a major problem, I was taking out the bushings that hold the bridge together, and I accidently dropped the wrong screw in the bushing and started to tighten the bigger screw that holds the tailpiece, then I realised the bushing wasen't lifting, turns out the screw was too long and got stuck, so now all work is halted until I can get that last bushing out, which looks like a pain to do, its really stuck in there, any suggestions?
