A rough finish is fine with me. If anyone cares about how smooth and shiny, we can always do a bit of sanding and get ou thte mag polish ourselves. As for price, I really have no idea what to say, could you give us a ballpark figure? I don't know how hard it is to machine something like that. Whether a set of cases will be 50$ or 500$ i have no clue.
I do know that i have spent a bunch on my MT2 already and the only things left stock currently are the diff cases, A arms, lower chassis, and battery box.
So I would be very interested in buying these diff cases!
