yes I have the Saginaw box from a 75 to 87 truck. (read my question) and as stated the tire rubs it badly. Keep in mind that my truck is a 3/4 ton. so tires are a lot bigger than most 1/2 tons.

I'm already spaced out at least 3/4 inch on each side with my hub conversion. And no way just adjusting the stop will help. I would have to replace the bolt with at least an inch longer one. and this might stop the rubbing but not the seriously reduced turning radius.
