I believe it all depends on the backspacing of the wheel. I have that size and it barely rubbed because of some cheap wheels that I was using for the drag radials. Get some welds with the correct backspacing and I sure they would fit.
That size sounds pretty standard and I think those are the welds we had before they were stolen off the car. I would just ask weld or one of the large mustang places when you order them to make sure, they will know, they sell tons of those wheels. Do me a favor and buy wheel locks, I know they aren't theft proof, but they help. Good luck.
