I just bought new 16x8 MT Wheels for my sub. The rear track width is a little narrower than the front... or at least it appears that way. Since this is my daily driver I want it to look great. So I would like to have the rear wheels out even with the wheelwell. So before I go do all the measuring, does anyone know how much spacer I am going to need, and is there a manufacturer who might have said spacer in stock and ready to ship? Thanks for the info. Oh, and I need them for the 3/4ton 8 lug truck.
