Dealer Where Your Mopar Was Sold
mine was in the owners manual and the Certicard under the hood
When I last checked it was still in business. With the shake up and dealer drop outs last year should check again and then see if the original owner is still living.
I had a 68 Dart Convertible parts car (Boston) and my 67 dart convertible. I was surprised that both cars came out of Mass.
