Track adjusting cam variations
I have 2 different track adjusting cams (both are unmarked). The size of the holes for the bar are different: one cam has 11/16" holes and the other has 7/8" holes. Obviously for different bars. Maybe a Canadian vs. T16 variation? There are 2 different cams listed for Canadian carriers: -B and -C versions: maybe they are different? Any comments on the diameter of the bar commonly used on Canadian Carrier cams?
