We just did mine , with 885 X's and 5100's set on zero. I also used both spacers on the drivers side, for the lean. It was almost to the point it would not go together, but it eventually did fit, the passenger side went in alot easier,with only the 1/2 spacer on top and no taco lean spacer. I also put new isolators on my coils from Wheelers, and they were pretty thick and may have made installation a little harder also. Right now my truck is at 3.5 inches over stock, it's a 4 cyl. Ac 4WD - I don't think it's going to settle much. The hub to fender well measurement is right at 23.5 on both sides,a little more than I wanted. Good luck,somebody on here should have some good tips on installing them for you.
Got any pics?
