Here's a brief history of the car that I've gathered from the build sheet and the fender tag
The car was built on Jan 16, 1969 at the Hamtramck, MI Plant with a 440 Magnum V8 375 Horsepower engine. Here is a pic of the Fender tag (this is bolted to the frame of the car and breaks down all the options that were put onto your car in the factory). I have broken down all the codes for you from the bottom to the top, left to right.

Now I've spoken to the owner who I brought the car from. He said he brought the car from a guy in the Bay Area. The pink slip show's the car was brought by this guy in 1976. Doing a people search on the web I was able to find the new address for this owner and sent him a letter asking for any history of the car. A week or so later I received a email from his wife who said that they indeed had owned this car, he brought it from a used car dealer in San Jose, CA in 1974 or 1976. He does not remember the dealer he brought it from.
