okay so im heading to the junkyard tomrrow to pull my coil seats...one problem he does not have a 91 4x2.....Although he does have a 92,93,94,95,96,97 and has all them in f150-350 sizes. So guys I really need the year of the truck that i need to pull off, and need to now if i need 4x2 or 4x4 and i need to know if the higher the Number on the truck( F150,250,350) does it equal to more lift? Thanks guys i have searched all over the forum but really cant find all the answers. Thanks
