The build sheet can be found in various places, under the rear seat, behind the rear seat back, under the dash or carpet, on top of the fuel tank is where I found mine. Unless your car was built in Canada the VIN won't be of much help. GM in the USA didn't keep any information until 1977 on the cars built here. Keep in mind that sheet may have been found and tossed a long time ago.
