You don't have any drop. screw the drop srew down one full turn. Raise the glide bolts. The ends of frontrail should float so they are pressured down slightly by the cheek blocks. That should give enough dip to set the whip adjustments. 2 1/8 is the stock measurement on a S&S bass. 5 1/8 fro the center pin to the center of hammer molding. David has the right way to determine bore.
