Try this one:

Or measure the diameter of the hole and go to Home Depot. They have a special section.

I have the other side. Is this a serious answer?

If you pull the other one off, it may have the part number stamped into it on the back side. If it does, you could go to a local dealership with the part number and buy/order it from them, or try an online search with the part number to find a retailer to order from.
