JR Motorsports and Hendrick Motorsports to Join Busch Operations in 2008: JR Motorsports and Hendrick Motorsports will combine the two companies' NASCAR Busch Series operations at the conclusion of the 2007 racing season with plans to field a joint effort beginning in 2008. The partnership will campaign two full-time race cars under the JR Motorsports banner that utilize Hendrick Motorsports engines, chassis and vehicle engineering support. Rick Hendrick will be listed as car owner of the #5 team and Dale Earnhardt Jr. will be car owner of the #88. To support the operation, approximately 30 employees, including crew chief Chad Walter, will move to JR Motorsports' Mooresville-based facility from Hendrick Motorsports' Busch Series group in Concord. Walter will serve as crew chief of the #5 team next season.

So I wonder if one car will still serve as the primary ride for a Busch series driver while the #5 car will be used for several developmental drivers?  And what happens to the #24 Busch team?
