A simple way to see it all is to get yourself a spool of thick string and some duct tape. lay out strings laterally from matching points on the frame such as rivets, holes etc, then run a string from the rear most centerline to the centerline of the front x-member. then lay out some diagonal strings from matching points, stand back and have a look, it makes it very visual and easy to see if there is a problem with the frame.

I learned it from a thread here on the board,(http://67-72chevytrucks.com/vboard/s...d.php?t=627050 ) very helpful...
