Input: Question: How long had Nazareth Speedway been in operation for the year Elliot's team switch to No. 66? Passage:Geared up for a full run in 1997, Diamond Ridge & Sadler went from unsponsored to receiving backing from Phillips 66. The extra funding made a difference as Sadler captured his first career victory at Nazareth Speedway. He went on to post additional victories at Myrtle Beach and Gateway. He finished fifth in points that year. Diamond Ridge also expanded to a three car operation in 1997, purchasing the No. 1 DeWalt Tools team and fielding a car for Sadler's older brother, Hermie. Hermie had two poles and finished tenth in points in 1997. Diamond Ridge also fielded the No. 8 for Jeff Green, who won at Las Vegas Motor Speedway and ran fourteen races before he moved to Cup. In 1998, Elliott's team switched to No. 66 in order to accommodate their sponsor while Hermie moved into the No. 29. Hermie had a season virtually identical to 1997, posting two top-fives and having another tenth-place finish in the championship. Elliott scored three victories and finished eighth in points. Unfortunately, Elliott, who Diamond Ridge hoped would be their future in Cup, signed with Wood Brothers Racing. Still, hope was not lost. In 1999, Bechtel merged his Busch program with Joe Gibbs Racing, to field the No. 4 Lance Snacks Chevy for Jeff Purvis. While Purvis did not win that year, he had twelve top-ten finishes. The team fielded the No. 29 briefly as a second car for Curtis Markham, but sponsorship problems kept that from turning into a full-time ride. During the season, Bechtel eventually lost interest in the team, and sold the whole of the operation to Gibbs. Diamond Ridge Motorsports never returned to Cup as planned. The number 29 later went to Kevin Harvick in his first season in the Cup Series replacing Dale Earnhardt.
