400-series tailpiece with Tune-O-Matic bridge

Because these tailpieces were installed inconsistently, you must provide us with the distance from the center of the crown on the 12th fret to the center of the three tailpiece mounting holes in the guitar body so we can put the mounting studs in the right place relative to the tailpiece (proper intonation and all that).  If this is new construction or if you don't mind potentially moving the tailpiece, we can put the studs in a standard location and you can position the tailpiece accordingly.
