I know for a fact that GM offered 16" wheels for 1/2t 2wd and 4wd in 71/72, maybe later. I think they were 5". They would have been most popular in the mountain states where folks who "need" 4wd and "know" what works best out of necessity. They are like a dozen needles in a haystack to find (a dozen isn't much easier than one). Those black steel wheels will do ya, just not a stock look. But not a boulevard look either. There have been white spokes made in 16" with 12t pattern forever. Back in '82 or 3 my buddy (now brother-in-law) put some on a '77 Bronco with 9.00-16s. It was a beautiful all original brown w/white fancy model and this was back when everyone was hacking the fender wells, slapping flares on (usually just the rear for a halfassed look) to put wide rubber on. 16s are out there if you decide to go that way.

Not sure what to tell you on those wheels with the enlarged centers. I have run non-hub eccentric wheels with no issues, but your needs will put that to the test.
