Calling all Illinois guys!

[Hylton]

Guys, I am hoping that one of you can help me. Anyone grow up in or hung around the Heyworth/Normal Illinois area in the 1970's? Reason I ask is that I am trying to find the original owner of my 1969 RS Z/28. The car was originally Burgundy with white interior and white vinyl roof. It also had an endura bumper and remote mirror. The earliest owner I could locate was Larry Bartosik who bought it in 1977. He thought that he bought it from Chris Slupionik who was well known in the area for building street rods. After talking to Chris, he said he remembers the car but never owned it so I'm back at square one. Any info would help. Even if you might know the name of the dealer who was around there at the time.

Thanks!
