CHARLOTTE, N.C. — Richard Petty Motorsports is finalizing elements of its 2010 program, beginning this weekend when Elliott Sadler will race a Ford at Talladega Superspeedway.

Behind the scenes, the team is also shoring up its lineup.

Team officials familiar with RPM's personnel moves told The Associated Press Wednesday that sponsor Best Buy will move from Sadler's car next season to Petty's famed No. 43 with AJ Allmendinger as the driver. The officials spoke on the condition of anonymity because the changes have yet to be announced.

Stanley will become the sole primary sponsor for Sadler. Both Best Buy and Stanley had shared Sadler's car this season.

Sponsorship concerns have been one of the larger issues facing RPM as it prepares for 2010. The team is trying to complete a deal to merge with Yates Racing, and plans to move full time from Dodge to Ford next season.

Majority team owner George Gillett Jr. said earlier this month that RPM would field a minimum of three cars next season, but he would not discuss the potential lineup or sponsorship issues.
