According to my Catalog, I can get front fenders for a Fox body that do not have the mounting holes for the ground effects and are listed as fitting '79-'90. Or I can get Fenders with the mounting holes that are listed as fitting '91-'93. Is there a difference in Fox body fenders between '90 and '91 besides coming with the holes for the ground effects? Like how they mount to the car? I posted this here because I didn't think it belonged in the Tech forum. Thanks for your opinions.
