KANSAS CITY, Kan. (AP) -- James Hylton gingerly climbed out of his No. 48 car after an ARCA test at Kansas Speedway on Friday, and nobody could blame him for moving a little bit slower than his competitors. He's 79 years old, after all. The oldest driver to race in each of NASCAR's three highest divisions, Hylton was calling it a career after Friday night's race. The Cup rookie of the year in 1966, Hylton has spent the last several years of his career racing in the ARCA series.
