Here is my car soon after purchase, circa 1979. It has/had PO6 when I bought the car. The rims have body color paint, but over the blue paint is silver paint? Whenever it was done or whoever did it, the tires where not mounted as the silver is on the inside where the tire mounts. I just so happen to have these in there as found state & can get a pic later. I am not saying these are factory how the rims left and I am not trying to muddy the facts. I know of no other pic on the net showing them the way I describe.
This is a 3 owner car & I can call the prior owner & see if he did this, but it will be awhile.
