We used to run 17" on our 3/4 ton GMC 60 to 70 years ago. As far as I know, they were Kelsey Hayes. To me the most desirable one was the three piece. I still have some 17" wheels with junk tires on them. I will try to get some photos. As for the GMC site, I have heard several instances where registration was denied. The administrator and I discussed this several weeks ago. I will contact him and let him know that he problem still isn't fixed. GMC ownership is not a requirement.
