Made some some more progress. Had to exchange the existing differential to the supplier for a different model. Problem I ran into was the offset V1 placement on the frame. Being a pedal version the motor naturally sits right underneath the driver yada yada yada. So the motor and the drive sprocket are offset. Existing differential RH axle half wasn't long enough as a result. Here's the different model differential on the bike now. The only issue now is the axles need cutting to size and threading on the ends.
