WOW!!!
Neat looking car!!
Remember back in the day.....somewhat......that Indy car drivers raced other cars within USAC, from midgets to sprints to Champ Dirt cars(the latter at that time, part of the Indy car "trail") and their stock car series.....
The last photo before all things were put back together, I could see a diorama of this one with the complete frame as shown, then hanging above it, the interior section, followed by the roll cage and the body hanging about it all....!!
