I am doing a 52" conversion on a 69 1/2 ton and putting a 60 and 14 in it for the guy while I am at it. I am curious how far forward you guys moved your front perches to make the tire sit in the factory position in the wheelwell. He is not a fan of trimming or an uncentered wheel. Still drives it to work sometimes and such. I currently have them moved 4.5" forward and the rear shackle perches moved 2.25" back and a 7 inch shackle. Isn't on the ground yet, wanting to know what is might look like (still dont' have u bolts and other goodies to set it down with.) Will the tire be centered? rear leaves are 1974 1/2 ton 4wd rears with the overload still in it.
