Dale Earnhardt Jr. will reveal his 2008 number and sponsors in a news conference at the Dallas Convention Center next Wednesday, Hendrick Motorsports officials announced Thursday.
Sources confirmed earlier that Mountain Dew and the Amp energy drink, both PepsiCo Inc. products, will become two of Earnhardt's primary sponsors next season.
The announcement is coming in Dallas because PepisCo Inc. executives are having an annual conference there next week.
The National Guard, which now sponsors the No. 25 Chevy of Casey Mears for the Hendrick team, is also expected to move to Earnhardt's car in 2008.
The No. 25 is being eliminated and Mears is moving to the No. 5 Hendrick Chevy, which is sponsored by Kellogg's.
Earnhardt and team owner Rick Hendrick have managed to keep the new number a secret, except to say the number 8 will be involved in some fashion.
Robert Yates Racing, sources said, has agreed to sell the No. 88 that Dale Jarrett drove to the 1999 championship.
Hendrick officials and Earnhardt also will reveal his car's paint scheme for 2008 at the news conference.
