I know this is another old thread but it has some good discussions and questions.

I have a 1 ton 52 Chevy pickup without frame extensions and a 51 GMC flat bed with them, though they've been torched some to mount a hitch.

Trying to swap the pickup bed to the GMC and want to know more about these extensions.

Does anyone have detailed drawings of the extensions in case I need to remake mine?

Any answers as to which model 1 tons have them and why?
