[s-cars] part number for the center caps ?

[Pollock, Thomas]

Ok you family album gurus'....

I'm stricking out but I know it can be done. Can someone tell me the part number for the black acrylic four ring insert that goes on the S4 OEM 16x8 five star center caps ?   I know someone who ordered some from the dealer way back and of course no longer has the number, so I know it CAN be done.  Dealer couldn't find the number and claims you have to buy the complete center cap. I only want the black acrylic piece. I suck at using ETKA but it looks like this part really isn't listed, confused cause I know someone who HAD bought some.

any help out there ?

thanks,

tom.
