And axman we have the same gear ratio and tire size. Get the wine colored 16t driven gear with the 7 tooth drive gear. I just don't know what the number for it is or the color Number Dumming is in the prosess up helping me out with that. As ctubutis said its probably the wrong parts in there or the case coould have come from another vehicle and has the wrong drive gear, because a 19t is nowhere close to being right.
