Blown T, I am using a Quickor 1" front and 7/8ths rear bar. I have "NO" problems with the front bar. I don't understand why you don't have any clearance. DonI have a problem with the Addco 1" bar fitting. There is no space between the bottom of the frame and the top of the lower control arm with the 1" sway bar in there. The bar is sitting in there with no bushing or U bolt to the frame and I cannot move the bar away from the frame to add the bushing/bracket.
I am thinking the Rare Parts offset eliminator kit moves the front of the lower control arm up and reduces the space allowed for the sway bar. Guess I need to put the old 5/8" sway bar back in but I have to take the whole frontend apart to do that thanks to all the bends in the bar.
