I've had a pair of these sitting in my Summit online shopping cart for a while.

I think the truck would really look better with fatter wheels in the rear. If i do that, I'll put together a set of thin whitewall tires at the same time. There's a guy on here who does that a lot (Yezzi?). My front tires are very new and whitewall already turned inside. I could get a pair of matching rears and sport big and little steelie wheels with thin whites and dog dishes.
I did the same look about 10 years ago on my 72 one ton to half ton short bed conversion truck.
