1970-72 K20 Frame Dimensions

[Cole Pete]

I have recently purchased a group of project trucks. Among the items I bought include a k20 frame that was hit in the side and is slightly tweaked. I'm wondering if anyone has frame measurements/dimensions for a 1970-72 K20 frame? I'm currently in an auto collision program at a tech college in WI and my Instructor is thinking about letting me use my bent frame on the schools frame rack. I would like to find some dimensions to go off of while I straighten it to make it easier and precise. I've been searching the internet and haven't found what I'm looking for yet so I thought I would check on this website. If anyone could help me out and lead me in the right direction it would be much appreciated.
Thanks!

Welcome to the board!

The information you need will be in the factory "chassis service manual" section 2 for any of those years. Look up KA209 for a K20.

Go to this link and download a manual.

The online resource is great to have but the manuals do have image degradation. Otherwise I would just post the relevant pages up for you.

But this is what you can expect for information.
Now you owe us a picture or several of your trucks.

Thanks for your help! I'll put the info to good use and i'll have to get some pics of my project on here. I appreciate the help.
