looking for frame dimensions

[GreaseDog]

Looking for a diagram of frame dimensions, including suspension mounting points and body mount locations for an 80 K20. Anybody know where I might find them?

I should probably elaborate for those of you not in the know. I'm working with a 1980 K20 frame, mounting a TBI 454 and 80e in it, and mounting a GMT 400 standard cab body on it, and probably building a flatbed. Actually planning on doing a writeup on the frame reconditioning, as it will get complete new suspension, steering, and a brake overhaul.

The frame dimensions are all the same across the 10-70 line. That means lengths & widths of structural members and the distances between them. Mounting point locations and thickness of the steel used in the frame will vary. But these spec sheets should be fine for what you are doing. The body dimensions are obviously for the C/K series:
