The 95 wheels fit over the cap.
The newer stang wheels will fit, but you wont have the center cap to the wheel.
The backspacing on a mustang wheel is around 6"-6.25" which is made for a car.
I had a 17x9 Cobra R with a 2" adapter to push it out. Mine cleared.
Theres a member on here , D , which has 01+ Cobra Wheels, with no center cap up front to clear the dust cap.
The wheels in my avatar, are 95 Cobra's and fit. Without any modifications.
My wheels are on a mustang right now though, althuogh i had them on my truck.
