I think I can now also provide a couple of pics of the I/SA winner. He's listed as: "Arnie Tofteland, LeVerne, Miss '71 Pontiac"
I ASSUME that address is wrong. I THINK he actually lived in Minnisota, NOT MIssissippi. NOT certain.
I think he drove at least one of the "Viking" Pontiacs, sponsored by Schoon Motors. I think the car on that list was a '71 Formula Firebird.
In my files, I have it listed as a '70 model, & it has H/SA on the side. BUT, for now, I'm gonna make a guess that this is the "71 Pontiac" shown as the I/SA winner. NOT positive !
The 3rd pic is of the Schoon Motors sponsored F/SA '70 GTO.
