You info doesn't state where you are located - but..
If you are fortunate enough to have a car from Norwood that you suspect may have been shipped into and sold in Canada - all of the information you seek could be available through GM Vintage Vehicle Services in Oshawa Ontario.
(Google it to get the relevant contact info).. if you have the VIN number they can pretty much immediately confirm if the car was ever in Canada and if so they can sell you a package of confirmed sale location, dates, and options as delivered.. you may just get lucky!
