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.

Just to set the record straight on 4x4 frames: K/10 Long bed and K/20 share the same frame. Short bed K/10 and K/5 are different frames from each other and obviously the long bed trucks. The short K/10 and K/5 both are lighter duty than the long bed K frame.
