Has anybody built a rear dually spacer for a 97 f350 drw? I am needing a blue print or drawing of the measurements for an 1/2" thick spacer for the rear only. A question I have is can it have the holes for the lug studs and the alignment pin drilled in it and the hole in the center for the hub only or will it have to have two sets of lugs drilled, one for the existing studs that's on the truck, and then have a set on the spacer for the outer rim to bolt to? Or are the studs that's on the truck long enough for a 1/2" spacer to be put between the wheels and still be able to put the lug nuts on?

 

Just buy them. They need to be hub centric.
