68 C10 Frame Specs?

[2nintey2]

I just joined here and have a body-off project in progress(for the last ten years). I spent several hours looking on here for frame specs because I need to straighten the frame. I found the ones posted on here, but when I enlarge the post, I can't read the data. I have looked for old frame manuals, but those things are getting harder to come by. The truck is a '68 C10 Short 2x4, can anyone help?

Once I get this thing is straight, the process is gonna speed up and I'll keep updates and pics on here. This was my first vehicle and it has been setting in peices for years, so this is gonna be a time machine build for me.
