There have been many posts on this topic, as you know. The OEM style trailer wheels did the job for many of us and now Wheel Vintiques are making wheels which I understand should fit. However, we now have an additional tool for the wheel search. If someone is willing to put in the time, the GM Chev specs for these older vehicles are now on line. It seems to me that one could look at the wheel specs for some of the 80s trucks to find a match.
