For the most part, Junior Stock was everything below the top classes. There was always a "Super Stock", designated as "S/S". In 1961 they created an "Optional Super Stock" class for specialty factory options. In 1962 and 1963 there was a "Super Super Stock", "SS/S". In 1964 and 1965, there was a "AA/S". Starting in 1964 were the Factory Experimental classes, usually an A, B and C class. These classes and the mixes in the eliminators changed from year to year. For eliminators, in 1964 the FX classes and the Super Stock classes ran for "Top Stock Eliminator". In 1965 and 1966, AA/S or A/S also was included in "Top Stock". Everything else ran for "Junior Stock Eliminator". In 1966, the FX classes got dumped into "Street Eliminator" with the Gas classes, Modified Production classes, Sports Car classes and Modified Sports Car classes. In 1967, the FX classes were replaced with 10 Super Stock Classes and the eliminators were confined to the Super Stock classes and Stock classes as we know them now.

Junior Stock generally meant the classes and cars that were common production combinations you would see middle America drive on the street and had been turned into drag race cars, not the specialty high performance purpose built cars that the factory produced for performance impact sales.
