I'm in the process of deleting parts for the Rear drive.
Basically, all this is eliminated.
The gearbox no longer needs to hold gears, so it becomes a support for the shock tower only. I had an old item that I remodeled into a more aesthetically pleasing shape.
I temporarily installed my kazama knuckles to play with ackerman... but I will be using a customised type C suspension, so this is just for "display" until my other parts arrive.
