Carl,
It's on my list! I can dig out the pre-NASCAR racing organization names but car classes will be a challenge since many of those records are lost. I'll have to add a day onto the June Norwwod Arena reunion to dig through the New England Race Museum and see what they and R.A. Silvia have. R.A. is a great data provider for this site. We all owe him!!!!
Thanks for the explanation! Admittedly, it was a bit difficult telling the divisons apart (except for the cut-downs) way back when. I do remember the wheels flying off the cars! Very exciting!
