After two months of waiting, I have received the part. This part is rare to find and I was amazed that they could fix it.
The center was chromed. Basically it is supposed to be sand blasted first then chromed. After I've sand blasted the center, two indentations appeared under the chrome.
I used body filler to correct the problem.
I've used this paint to simulate the original look.
The owner and I have installed the part a few days ago. The car is now finished!
