Yes '62 was the last year for the C40 according to the foreword in my 1963 shop manual.

As far as I knew only 1/2 and 3/4 tons used torsion bars prior to '63. You learn something new every day! I know that in 1963 all trucks went to coil springs.

I do know for a fact that 1962 was the last year for ball bearings in the front spindles. They started using tapered roller bearings in 1963.
