Donna, that is not always the best way to tell as different factories did their own way of doing bumpers. Some have the wrap around frame or the added on bumper between the frame rails. My son and I both have 1971 Bolers and his was built in Winnipeg with the wrap around frame and mine was made in Peace River, AB and has the straight frame rails with the welded on bumper. And who knows what mods have been made by previous owners.
By the looks of the pic, with the added dome on the roof it will be a late 1968 or newer. Only the first 100 had the flat roof.
Dean, what year does the Insurance paperwork and Bill of Sale say it is?
Note many were never registered properly.

? That will help.
