O.E. Wheel Distributors in Sarasota, FL. is where I bought mine (866-273-3651). I paid $590 shipped for 18x9/10 anthracite Bullitts. The price included the mustang center caps instead of the Cobra ones. They are great looking wheels. One of mine had a ding in the bead that does not appear to be shipping damage but a defect. They immediately had it picked up and returned at their expense. They received it Tuesday afternoon. I am awaiting a call back at the moment as they said they had to determine whether it was shipping damage or a defect before they would just send one out. I'm starting to get a little impatient but so far they have handled things well.
American also makes a very similar wheel but they are more expensive. They are great looking wheels though.
I will post back on the customer service handling of mine later.
