I have a 1987 black convertible 5.0. I almost have my girl the way I want her except one thing. Five lug conversion and lower her a bit closer to the asphalt. As you know I can't begin any of this until I get a new set of wheels and tires. So does anyone know what wheel offset I'll need for 17's to fit inside the front fender well so I can lower her? Thanks in advance.
