Billy Johnson driving the #43 at Sonoma:

Richard Petty Motorsports announced today that IMSA Ford driver Billy Johnson will pilot the #43 Smithfield Ford at Sonoma Raceway and fill in for the injured Aric Almirola. Fresh from competing in the 24 Hours of Le Mans, Johnson will make his first Monster Energy NASCAR Cup Series start this weekend, but this isn’t the first time he worked in NASCAR. Johnson made five starts in the NASCAR XFINITY Series and scored a career-best eighth-place finish in Montreal in 2012.[More]
