68 camaro L78 at St. Louis Raceway Park

[L34Pace]

I'm hoping someone here might be able to help me find the original owner of my L78 camaro. It was ordered at Bill James Chevrolet in St. Louis. I have the original POP, window sticker, and dealer invoice but the problem is this guy put everything in his mothers name, Ruby Helnike, for insurance reasons. The car is cordovan maroon w/a black vinyl top. It is a factory M22, BW 4.56 and was known to race the 1/8th mile at St. Louis Raceway park from 68 to the mid 70's. His first name might be John with possible last names of Helnike or Morgan. If anyone can help put a name to this car I would appreciate it

Thanks
Pat
