I'm looking for a Floyd Rose locking nut with the old style through-neck mounting screws, preferably in black. It's for a Kramer Focus 3000 neck I found at a garage sale. The neck measures 42mm wide at the spot where the missing nut goes. I can only find 43mm-wide nuts (and mostly of the new top-mounted variety) on eBay. Anyone know if Floyd ever made a 42mm width?
