Cut holes in the chassis where the spool and diff pulley will be positioned (make the existing holes bigger). Than flip the belts and place the electronics as far to the middle as possible for better L/R balance. Finally drill a new hole for the servo holder and only use the normal shaped servo holder, so loose the L-shaped one. The servo is now 6mm shifted to the middle.
