Not sure if the mounting hardware for the car assembly line was supplier by the provider of the shock as it was in the service shocks. If it was then there is the chance that the finish might be different between the car assembly plants since not all of them got the majority of their shocks from the same supplying plant. We see the MADE IN CANADA shocks the majority on NJ and Dearborn car plants and MADE IN USA on San Jose cars typically. This may not be a factor just wanted to mention the possibility. Also may have changed during the production year
With all that out of the way here is at least one example that was easy to find from on of the San Jose examples that is in the Unrestored Picture section of the site
Did look further but not a location people often take pictures of and not an easy area to get a clear picture of
Original take off's in the upper left (MADE IN CANADA with 67 date codes) but the finish is long gone on the hardware. And a picture at a bad angle for your needs of a MADE In CANADA on a Dearborn car
Due have NOS service packages (pictures) of the front shock hardware. There is the earlier style with the toothed washer and the later with the deformed nut style locking nuts. Didn't post since they are service pieces.
