I just got a BP21 that I plan to use in a GWS Zero & GWS TM400, and my understanding was that the gray plastic mount is a direct swap for any GWS stick mount. The plastic mount that came with it does look like it will fit, but I can't figure out how to mount the motor to the plastic mount. The plastic has two screw tabs, but they don't line up with any of the three holes in the aluminum back plate of the motor.

I can get one to line up, but then the motor is off center.[sm=angry.gif] I figured I'd just center the motor and drill three new holes in the plastic, but the holes in the aluminum overlap the edge of the plastic when the motor is centered, so you can't drill three holes.[:@] HELP!!! What am I missing?[sm=confused.gif]
thks, scott
