Rivalries have always been a part of NASCAR history. They began with the first Strictly Stock race on June 19, 1949 at Charlotte, N.C. when Jim Roper drove into victory lane for the very first time, He did so after race winner Glenn Dunaway was declared illegal for having leaf springs at the rear of his Ford. From that day forward, drivers have expressed their unhappiness with other drivers, especially after being sent sideways on the track followed by angry comments on pit road or the garage area. From the 1940s through the 1990s, there were plenty of legendary drivers that kept fans on the edges of their seats with the latest skirmish in the headlines. NASCAR historians Ben White and Jerry Bonkowski look back at many of those stories in podcast No. 64 of "A Lifetime in NASCAR, as well as the origins of the car number in this episode. Give "A Lifetime in NASCAR" a listen for some interesting information on this week's podcast.
