Changed the rear axle for a MRRC rear axle that already has the crown gear fitted as I would hope these are the correct crown gears for the motor offset. I have also had to slightly shorten the front mounting post as the car was sitting slightly high. It still doesn't look quite right but any shorter and the front wheels will be to far inside the wheel arch. I have also done some final trimming to the interior plate so that it fits around the mounting posts and iit just needs painting now and a drivers head.
