Hy Tomm, now that we at least know the year and size of the truck in question, could you tell us the thread size of the studs you have now. I am going to assume you have ten stud wheels on the 8 3/4" bolt circle. The stud section is a large one in the parts book and there are at least two different thread sizes listed 11/16" X 16 t.p.i. and 3/4" X 16 t.p.i., the parts book may not list studs that are long enough to allow mounting of aluminum wheels, but any info you can give us will help to track down studs which may be long enough.
