Wheel Identification / Need new center caps

Hello, I am looking to purchase this 2013 Explorer XLT. Here is a pic from the ad, showing the wheels on it. They are made by Ultra. I would like to swap the centers for silver / chrome ones. Does anyone know where I would look? I tried web searching to no avail. Any leads appreciated.

Contact the manufacturer, http://www.ultrawheel.com/wheel/4372/245-spline-cuv/

It looks like those wheels come in two other finishes.

THANK YOU so very much. That was exactly what I needed. Found out there is a dealer in town so I'll hit him up for prices.
