#1 out of my element... a handful of trips to Shangri La/Tioga Motorsports Park... and Five Mile wasn't on the radar until a couple of trips in the nineties, then worked a season there.
#2: Don won at Shangri La, Syracuse, Five Mile Point, Lancaster, Lebanon Valley, Spencer, Reading, ...that's seven. Thinking maybe at Oswego in a super...that leaves two... wild guess, maybe a big show at Weedsport, Fulton or Fonda...
# 3. Mario Andretti and Dan Gurney immediately...grey hair made me stare at the wall for a bit then remembered Montoya's WGI NASCAR win.
#4. Plymouth, Ford, Oldsmobile, Pontiac, and...crap! Drawing a blank. If I had to guess I'm thinking Buick...don't remember a Chevy, but could have run a convertible race with one.
