Well, I believe it goes together just about the same way as the TC3's diffs & gearboxes, so you might be able to adjust it the same way, by removing the wheel on the side of the diff where the adjustment screw's head is, then popping off the turnbuckle on that end(the camber link) & let the hub pivot down & away, then you may be able to reach the screw with a sufficiently long allen wrench.....
