This combo states that it will fit all 79-93 mustangs, but in the description it says it will be a direct fit for 87-93 mustangs only. Will My 85 Mustang run into problems with this combo? And if so what modifications will be needed for it to fit? Last two questions is fitment an issue because of the tires because id rather not modify my mustang, can I just buy the rims separate and order smaller tires? What will be recommended? Sorry for all the questions and thank you!
