We ran 30X9 on all our Foxbody cars with the stock width 8.8. The backspacing just has to be right. Can't remember if it was 4.5 or 5.5 that worked best. These are low HP cars, no need for a 10 inch rim, 7 or 8 will work just fine. As far as wheel well openings 87-90 cars are bit smaller than the 91-93 because the standard wheel was 15 inch and in 91 they went to 16 inch. You will have to open the front side of the wheel well some and hammer the inside next to shock some but they will fit. NO adjustable lowers are allowed in stock. There are many different manufacturers for lowers that will work. Run the double adjustable uppers and make sure all the bushings in the rear are solid. We ran an air bag for years that worked but the anti roll bar worked better. Fun combination and very reliable. Good luck!
