Billet case required

We require assembly to be checked in a window case. That is a "cut top half case on 4 sides to see thru window, to make sure all lines up and engages fully and smoothly. Simulates a locked in top bearing and fully functioning gear set."

Saves hassle and risk of doing damage putting it in the car blind.
