I am rebuilding an electric guitar that I have had for 30 years. (since high school) I had the bridge and bridge screws re-plated and the grooves in the screws have closed up enough with the nickel plating that the bridge does not fit in the grooves now. I am sure it would be a simple matter for a feller with a lathe... I would pay for ship both ways, (obviously) and your time.
