Cool. I live about 20 miles from Hillsboro, Ohio. Welcome aboard. Guessing you are in Fla? By the Boca reference. If you have owned this since 89 that would be 20 years of owner history needed. Seeing the car was in another state when purchased, this could be difficult and it could be easy. It depends how many owners it went through and how far it has been separated from its original surroundings. Knowing where it originated is a huge plus. I would start with an ad on Craigslist under cars for sale, car parts for sale and general topic posting, yes, all 3,maybe some other section with a picture of a pace car and inquiring if anyone remembers one sold new in Hillsboro. This is a small rural agricultural town, so someone may remember. If I can be of assistance as a detective, PM me. The wife works at the hospital in Hillsboro (Highland county) The dealer is now Jerry Haig Chev. I would also use Facebook
