Donna Mae's Sprite is in Springfield, Mo. being restored by Jeff Moore of Automotive Archeologists. Donna Mae was nationalchampion in that Sprite in 1963. Jeff also has several Yenko Stingers including one of my old ones that Grady Davis purchased new. Donna Mae was Don's secretary and is still a blast to hang around with.
Here is a link to Jeff's site with pictures of the Sprite.
