Thanks very much Turna. Could you tell me which book you have, that you posted the photo of the production numbers? Its something that I've been trying to figure out. I've done some research, and read on another site that there were 202 4 speed Malibus sold in the States in 1980, and 124 4 speed Malibus sold in Canada in 1980. I intend to get in touch with GM Vintage Vehicle Services here in Canada, and have them check through the VIN for my car, to see if I can get some more info on all of the RPOs on the car (I have the original bill of sale, from the dealership when the car was sold new, but it doesn't have all of the info that I'm looking for), and I'm hoping that they can confirm the actual production numbers, at least for Canada, for 1980.
Regardless of the actual numbers, I know that I have a rare car here, and that not many were produced that year.
Thanks again for your help.
