GMC Wheel Cover Plus (?) w/WIW Question
 

Recently came across this GMC wheel cover but it has an added " ring " attached to it ? Never seen this style before and have been wondering just what it fits. It is in the style of the PO1 full wheel covers but measures 16 1/2'' across from edge to edge. Cap itself is inreally nice condition with all five faux lug nuts present, some normally found black paint missing from the cap, few very minor scuffs/dings. Nice 10 footer maybe even a 5 footer. Just never seen this style with an added ring mounted to it. What does it fit and a value for it would be much appreciated.

That ring is to use PO1 covers on 16.5 wheels

Hmm, have never seen PO1 wheel covers on the 16.5'' wheels. Been playing with these trucks for a good many years, never knew such an adapter as that existed. Would that have been used on the larger 30 series motor homes also maybe? Any idea of the value of such for listing in the parts forum? Both the adapter and wheel cover are in nice driver plus condition.
