I just ordered 4 2007 Cobra Style Black Machined rims off americanmuscle.com ( http://www.americanmuscle.com/17x9-4...machblack.html ) and tires to go with. My only question is what exactly will i need to change out to fit these? I only know I need the 87-93 spindles from the front, but I don really know what else. Please help me out!

My car is a 1985 Mustang GT Vert

Thanks,
Chad
