I was there too with my 67 GT 350. Checked all my photos, but, sorry, none with your car in it.
But, I'll tell you. Mid day after lunch, a Dodge mini-van showed up in the show parking lot. The van had "official vehicle Indy 500" decals on it. And out pops Carroll Shelby. He instantly got mobbed.
The show officials had Carroll sit under a tent, and he signed autographs for about an hour and a half. Then Carroll stands up and says "lets go sign some cars". And off he went, car to car. Was a great day to be there.
