Nice purchase! I have always thought that car was well done. I believe Chuck Hanson owned the car but bought it already converted to 4-speed. Mr. Hanson was president of the late ACES (American Chevelle Enthusiast's Society). I don't have contact information for him, but occasionally he hangs out at Team Chevelle under the user i.d. ACES1

The closest thing I have to contact information can be found here: http://www.chevelles.com/forums/members/2485-aces1.html
