Yesterday I installed my Gen1 AWD Kit. Now my front Diff blocks my GPM tie rod, so i can steer left, but not to the right. The part of the tie rod where the servo plugs in hits the diff.
You need to get a flat file and file down the front of the two prongs for the servo horn. If you make it so the front of the prongs look like the back of the prongs you should be Ok. Also you might need to file down the front of the tie rod where it passes under the bevel gear, I had to for mine. Hope this helps.
