+1. Having the pinion and spur on the same mounting plane makes chassis flex irrelevant. Any other mounting scheme has the possibility of slightly adjusted mesh when the chassis flexes (and it does). The best way I've found to eliminate forward/backward flex is to make a top plate that attached from the rear diff, center diff, and front diff.
