When I think "heavy 1/2 Ton" , I envision a C 10 ordered with heavy duty springs, 4 speed trans, 292 big six and lock ring wheels, the way it was none in the 60's. Then in the mid 70's, the BIG 10 package came along with a higher GVW, mainly to get away from emission requirements which 3/4 ton were exempt from. But the K 10 is a slighty different animal in the 1/2 ton world, it has the same frame ( section modulus) as a K 20 3/4 ton in the '67-'72 era. I believe this is what heligyspy was referring to.
