There's a 1st and 2nd gen on the Stocker list at the div 5 race. The 1st gen is an E/SA '68 Bird, driven by Ronald Prince. The 2nd gen is a K/SA '76 driven by Kevin Love.
Well, neither car made it passed the 1st round. I'm not sure, but I think that K/SA '76 Bird may be the same car that Mike Morgan raced last year. He won his class and 4 rounds of elims, at the US Nationals, then sold the car.
