Canadian Built 74 Plymouth Valiant Questions.

quite possibly a very early 74 , and they found themselves using up the last of the SB drum brake stuff. the 9" drum brakes used the 4" pattern through the entire 73 run. kind of like the 78 SE charger. leftover 77 SE parts were used up and ran 2,900 units and then the magnum took over the XS22 platform.
