I'm not sure if this is supposed to go in this forum or the "discussion and happenings" forum.. but I figured I'd try this one. .... I found these cool ribbed trim rings in the trunk of a '54 Cadillac. They are a wide ring that reaches all the way in to cover the "dog dish" cap and emulate a full wheel cover, and they look bitchin.. but I have no idea what they are or where to find two more to make a full set! They're 15" Can anybody help me out?
