William “Bill” Guzenski has produced hundreds of how-to videos for the automotive community. When not working in the Contact Center in Grand Prairie, Texas for CarParts.com, he’s attending race events and car shows throughout the country. He also loves to travel in his 40-foot motorhome, exploring abandoned mines and ghost towns. He’s currently building another car for Bonneville Salt Flats and will be campaigning a drag car at several events.
