Thanks Arct1k I appreciate that.
Yes thats the only way to do this. Sideways it would twist the axles to a bad angle..
About the HB Center diffs spur gear. Is it always the same size or can I get there what ever I want? More closely are these center diff cars only geared from the pinion?
The bracing I can make by my self, so its the thing what goes from side to the other side of the diff? So the diff mounts are solid?
Dang, this car will be a blast

, have to do some gearing calculations.
