History on Shelby show locations

All,

Below is a paragraph from a previous owner. He is aging now but was able to recall where the car won 1st place. I was wondering which shows these may be back in the early 80's:

"Mike all I can tell you is it took 1st in Jackson, MS, Dallas, TX, Chatanooga, TN, Tulsa, OK (4-6 times at the big Shelby show), 1981 Gateway Region in St. Louis, MO, Govenors Trophie in Springfield, IL,. I'll try to dig up some trophies and think about it and i'll get that info to you. I'll talk to you later. Rod Cookson"
