Actually it really has nothing to do with Canada (although that would
seem to make sense). I worked for GM back in the mid 70's to early 80's
at an assembly plant. GM was in the midst of changing totally to a
entirely metric based car and truck system in the mid 70's. Somewhere
along the line I think that they discovered that doing that would cost
extra money in parts. So the entire effort slowed greatly. The result
was that cars and trucks built in the mid to late 70's all the way until
the late 80's and probably even after that, were a mix of metric and
english fasteners. It was and is a real mess IMO. They should have
either converted or not converted IMO, but apparently going half way for
a while was cheaper. It was a real nightmare at the assembly plants for
quite a while.
