How can I find a specific car with only the VIN?

[L78M22Rag]

I have a 396 motor that was born in a 1967 Chevelle SS built in the Fremont, CA plant. I'm trying to reunite the motor with the car. I'm going to post the partial VIN and what I expect to be the full VIN so perhaps the owner of the car can find me.

Partial VIN stamped on the deck is 7Z151822

I expect that the full VIN would be either:
138377Z151822 for a hardtop,
138677Z151822 for a convertible,
138177Z151822 for a sport coupe, or
138117Z151822 for a sedan.

The motor was assembled on May 31, 1967 so the car would have been assembled late in the model year - in June or July of 1967.

I'd like to make a project out of my search for the car, so can anyone give me some direction or advice as to how I can find out where the car was last registered or how I ought to go about my search? Of course, I've googled the VIN and nothing comes up. Thanks for any help.
