Since I'm always lookin for the Pontiacs, I couldn't help but notice that the new RAIV powered Pontiacs won D/S & D/SA.
Rod Kister had won the Stock points championship in '68, with his big '60 Pontiac rec holder, also named "Big Iron". Then the '69 Judge was followed by a '70 Judge Big Iron.
Not familiar with the other driver's name.
John Thropp ran at least 2 different '57 Pontiac bodies.
