I'm tryin to get a different set of rims for my fox body Mustang. It is a 89 GT with a 5 lug conversion and Summit Prostars. Here's my question; Is there a way I can tell which 5 lug conversion my car has? I'm trying to find out if they used Lincoln/ Ranger or s-95(whatever the heck that is). The guy that has the rims says they will NOT fit on his Stang with the Lincoln swap. From what I've read it's due to the rotors being to large. This is my first Mustang so ANY input would help.

Thanks
