I had gotten into the 60-66 LCF (Low Cab Forward)trucks some years ago, & accumulated about 5, or 6 of them. I had a '65 L60, which was a 2 ton, a '64 L60H (Heavy Duty 60 series), which in 1964 replaced the L70 series that existed thru 1963, which was rated as a 2 1/2 ton, & two L80 series trucks (a '60, & a '65 model)which were 3 ton trucks according to the info., I had on them. This being said, there were C60, C60H, & C80 trucks. I'm guessing they would have been the same. Hope I didn't confuse you.
