I kind of liked the sqaure tail tank. Thought it ought to have more slope in it though. Through the aid of the computer here is a vision of the direction tail tanks could take at the Rumble. Fans would love it!!!!! Shoot, if there were just a few more of them they could uncork the engine limits and start a new class and call them super modified midget munchkins.
And on a more serious side. Here's the Munchkin during 1988 at South Bend.
