I had the same issue trying to get my arms to pivot in, it was super frustrating and took more griding than i wanted, but once i got mine ground and in it was all good. I then took it in for an alignment and they couldnt get the passenger wheel in and reccomended i run the driver side in the upper hole and the passenger in the lower hole to help with the camber, so thats what i did and when i took it back in they had no issue aligning. I also asked the people on the forum if anyone though it would be an issue but no one had much concern about doing that, so im still rocking it!
i also my kit was the 6" but with a 4.0L and supercab i only got about 4.5" of lift up front
