Pretty much anything that fits any other fox. Latemodel Restoration Supply (
http://www.50resto.com ) Texas Mustang Parts (
http://www.texasmustang.com ) and several others including Dallas Mustang, California Mustang, and The Tire Rack and Discount Tire offer various wheel packages for the 79-93 four-lug Mustangs in sizes from 14-18 inches. A real clean look on an LX 'vert is four-lug silver Cobra-R style wheels in 17".
