So which is it? Same place says yes and no. It's actually no, which means the VIN is fraudulent on it's face. This really isn't that hard to grasp.
Want to know what happened in California. Someone went into the DMV with a bill of sale with your bad VIN, no title, to a 68 car that was missing the vin plate. Since it had no vin plate and the DMV must verify it, it was referred to the CHP for inspection. Nobody bothered to verify if the vin was legit or search out the SO numbers, and just moved it through the system. They checked the presented vin against the stolen vehicle database, which would never provide a hit, and whitewashed. The car was given a vin (bogus) that could have NEVER been issued to a 68 B body car. I'll guess whoever did the "work" had someone available on the inside to "help" with the process.
You clearly have a 1 of 1 car, if that's any consolation! :D
