OK here comes.... You're not going to believe what they look like!!
We used to run a series called Chump Car. White car is an 85' Cougar and red car is a 68' We didn't run the red car much. But we have wins with the white car at Nelson Ledges (25 1/2 hr race), Daytona (14 hr race), Lime Rock, Watkins and New Jersey.
Epic! Had to see some pics after reading your description in the first post. I understand why people asked if it caught on fire. Lol
