The correct part number for this is All Parts BP-1000-003 and it's known as the Schaller Style Tremolo Arm for Floyd Rose. It fits ALL OFR and Import/Licensed Floyd Rose Units and features a through pin that not only keeps the arm from continually rotating, but makes it effectively one integrated piece of the bridge....
NOTE: if you have a Floyd Rose 1000, you already have this arm. If you have a Floyd Rose Special, you need this arm.
