Looking at this auction and ebay user "Joparts" is one of The Parts Place user names..... Notice how clean, pit free, crack free the cap is??? Unless he had an NOS one that was placed on this wheel... View attachment 453329
Unless it says NOS it is a reproduction. He does this. Bought from him before. He is referencing the GM part # only. Bought a pair of NOS door sill mouldings only one was NOS because he says "exactly as pictured." Also if he says " new ", you have to ask if it is damaged. This happened on other parts .
