Here are 2 Vintage 14" OEM 70-80's GM Buick, Chevy, Pontiac Spoke Hubcaps. With a little work, cleaning and polishing they will look great on your vintage GM car. I do not have the center emblems. They can be purchased aftermarket. 

They would also look great on the wall of your man cave, garage or business. 
Another new fad is using vintage hubcaps on rat rods instead of aftermarket wheels. 
I rescued over 500 hubcaps from going to the scrap yard. I saw a trailer load of hubcaps and I asked the man who owned them where he was going with them. He said to scrap. I bought them and I am doing my best to find someone who needs them. I price them low and do my best to show any defects in the pictures. Once these old hubcaps are gone there will not be anymore. Thanks for looking and I will be listing more as I sort through them. Priced to sell.
