Thanks for explaining the CA measurement. I went back and looked at my books
1960 U.S. shop manual says CA DIMENSION ( 1 1/2 ton & up )
1960 Canadian shop manual says CA DIMENSION ( 10,000 lb. GVW and up )
Now that you mention it I remember seeing those definitions in the Truck Data Book.
From The 63 Price and Facts book. C85 has a 175" wheelbase
