Lots of OH newspaper ads through that time period so ask your pops for more info that fsc66 Paul or I can try searching and maybe you'll get lucky?
Did he buy it new or know who did also what Chevy dealer originally ordered or delivered it brand new?
Was it on Lyman's lot for sale after trade date as being 1975, it could've quickly been traded off to another dealer etc?
Did he ever see it again in years later and where?
Any chance it sold new 100 miles away @ Kenny Chevrolet Johnstown then back there for sale used as Nov-75 ad below...stripes added for resale?
Good luck!
