CarCrazyGuy,
I answered your question right about the time the internet service was changed so all of the archived threads were lost.
Jim Lewis would be a good reference to contact. His nephew Tommy and I are good friends and we both dragged Van Buren back in late '60s and early '70s until the wee hours of the morning. Tommy severly abused his '70 440 RT Challenger street racing, but then that was the purpose of owning this type of car back then.
So much for the old war stories. I believe the dodge dealership at the time your car was ordered new was Dean Pearson Dodge. Prior to Dean Pearson it was call Hume Motor Company. Dean Pearson sold the dealership and the name changed to Fidelity Motors then Jim Lewis bought the dealership. My history on the dealership is a little fuzzy since I moved from Enid in 1982 but somewhere between then and now the dealership changed hands several time to finally it is now called Johnson's Chrylser/Dodge of Enid. Maybe Johnson's still have paper work on your car archived but it may all be lost since the dealership changed hands many times.
Good luck tracking down the history on your car. Unfortunately, the Feds have made the effort to search the history of an old car nearly impossible. Because of the federal privacy act the State DMV will only release 10 years of previous history, if you have good reason for them to give it to you.
