Actually Jac ran a lot without a wing. Wasn't like it was first time. Saw him win in the Vance car at Eldora with USAC. Had a picture of him that day on the cover of Open Wheel magazine. In the article he was said he enjoyed non wing more. Remember him years later running the 3 day national open at Terre Haute. Told me he would love to have a ride for Salem the next day.
