Hi, New to Stangnet. Just bought a 2004 40th anniversary GT convertible with 115K miles. It has the 5 spd and the 17" pony wheels. Does anyone know the bolt pattern of the wheels and if I can upgrade to an 18" or 19" wheel without scraping the wheelwells and messing up the handling. Also, the headlight covers are fogged and need to be replaced. Who is the best parts company to get Mustang accessories from? Looking forward to playing with my new toy. Thanks
