I just passed over this welcome forum and post yesterday a new topic in the Tag Team already before receiving the invitation to introduce myself here. Well, I'm an proudly owner of a 67 4 dr sedan (pillared) made in Canada acquired nearly 1 year ago. I hope have some doubts and questions clarified about the car and of course, exchange some information in this forum.
Thank you all and long life for the Impalas!
Your Canadian car has the luxury of getting a copy of all of the original documentation for a nominal fee of $75 dollars Canadian. The Canadian government required GM of Canada to maintain all of their records instead of throwing them all away like they did in the US at the end of seven years.
Yes; that is the place! Contact George Zapora (Vintage Specialist) at 905-644-4060 (Oshawa, Ontario). I am not sure what the current rate is for a copy of the documentation will be for you in Europe. But I am sure he can answer your questions.
