Chris:
Check out Classic Performance Products website:
http://www.classicperform.com/You may find what you need there. I would call their tech line and let them know what you have 3?4 ton and what you want. Let the tech walk you through the process. I don't see anything there for 8 lug wheels but it just may not be listed. If they can't help check with other vendors for what you need. If still no luck you might want to swap front end with the 1/2 ton. If you're not hauling real heavy loads I believe the 1/2 will work for you.
Hope this helps.
