If memory serves, Hendrick was full-up on sponsors for next year (with the exception of the year-to-year partial National Guard sponsorship on the 25), and Budweisers deal is directly with Jr. Well, that'll be interesting, Jr. has a Bud deal, but not driving the Bud car???!!
I was unable to find out how long GMAC (the other co-primary on the 25) is good for, but Lowe's is good through 2010, DuPont through 2008 with a 2-year option, and Kellogg's through 2009.
The question is who goes? Do note that Bud spent several years on the 25 with both Ken Schrader and Wally Dallenbach driving for Hendrick.
