Welcome to the site. Looks like a nice car that you have there. I also have a 1980 factory 4 speed/305 Malibu, which is an Oshawa built car, another one of the 124 built for Canada that year. I was fortunate that the person that I bought the car from, turned over the original dealer invoice to the original owner when I bought the car from him. If you're looking for documentation, look up Vintage Vehicle Services in Oshawa Ontario. For a fee, they will send you documentation on your car, as long as it was originally titled and sold in Canada.
