You can try and shift your gearboxes left and right to help but my misalignment goes to the 2 o clock position so I would have to lift the tranny box slightly too. The easiest fix I found is just to loosen the tolerance of the drive pin into the pilot shaft. You can see in the pic I've flattened the pin ends so that it has some play in the cup. Now the alignment doesnt have to be dead on perfect.
Molded parts can be very tricky from batch to batch. Maybe Tamiya has added more fibers or slowed the cooling to better hold the tolerance of the molded parts. I had one of the early release cars.
