On the Cobra, mount a piece of plywood in to the Cobra (from the front ), cut a hole in the center (so the wires can pass through) then mount the P21 to the plywood, ( in your photo, think of nothing but the thin plywood behind the quarter).

On the AB using the same kind of plywood, make 2 pieces about the same size as the stock aluminum motor plate. put one on each side of the fuse, screw/glue the together, drill a hole in the center ( for the wires) and mount the PJS 550E, the only problem with this is the motor is more exposed, SSOO if you crash hard it may damage the motor, so don't use big screws to hold the motor on, use screws big enough to hold the motor yet small enough to shear on a crash.

Did I paint a better picture this time, I hope so.

Well it's Bedtime for Bonzo, later ALL
