So it sounds like K10 and K20 frames are actually a lot different then. (And what "manuals" stated this, btw? I'd be interested to read it.) A lot of bad info floating around then it seems. An no, there is no "indication on the frame" of where the mount would go. I'd just have to measure 4" back from the current holes.

You can download the specs for your year truck and compare. It will give you material specs and frame modulus for the different trucks. i.e. my '85 K20 with the heavy duty C6P spec uses the same gauge frame material as a 30 but with the frame height of a 20. So, a 20 but different. Interesting reading if you have time to kill.
