I haven't put my body on yet, but after putting on my control arms I new something was up they immediately wanted to bind. Upper and lower frame brackets were out of whack and did not measure up the same from side to side. I did not have to remove them all the way I was able cut them partially away and tweak them with a pry bar & hammer, then line up the bolt holes, tack them, than try again for smooth travel before welding the rest of the way.
