Swing Arm for [HD2], [HD2M-B], & [HD] Models
Swing Arm for The Green Guard [HD2] and 'SLIM [HD2]' Models.
Note: Starting on 6/26/26, the four screw holes in the [HD2] Swing Arm were moved out a little from a 1" bolt circle to a 1 1/8" bolt circle. If you ordered your unit after 6/25/26, then you need the newer style swing arm.
