I was able to get the Aero Cap kit at the service center in Houston for $50. The web site shows sold out.
I was also able to also get my missing 18' Aero Hub Covers for $30.
It is not easy taking out the cap and replace with covers since its very snug fit. I was talking with the service tech and if you end up switching the cap and cover it you might scratch up the small caps.
I got both so I'll probably put on the Aero covers and lug nut covers then keep the Caps on the side or sell it.
