Okay, I have tried everything and every site to get some information on my 1970 barracuda. I bought it 20 yrs ago with a title but lost it and I am trying to get some history on it so I can try and get a title. Every site I have tried has no history of the car or says invalid VIN # since it is only a 13 digit VIN. I purchased the car out of Columbus Ohio from a gentleman who never registered it. Does anyone have any ideas what I can do to find some history on the car? I live in Canada which makes it harder to get a registration from Ths States. Thanks for any and all help
