1.drill the trem bar slot to a certain length.(note only 20 % chance you can do it perfectly,really not recomended unless ur good at a drill)
2.Drill again but replace the drill bit change the drill bit to a size bigger and slot in virgin threads into the newly created hole.(50% chance of success this time)
3.the easiest.cut yer strings and get urself a new bridge.try a wilkinson bridge or original parts.(for sure can success.)
good luck
