I remember these cars so clearly even though I was a kid (except for the Bullfrog one). This was the aesthetic high point for NASCAR as far as I'm concerned. They never looked cooler than this!
I assume that firewall makes it hard to fit anything but the Rat Roaster hood? (if you were planning on using a hood). I'm just curious because I'm building the 5-window now, and I deciding what parts to take out of the RR kit I have.
