I am close to putting full air ride suspension on my '84 CCSB, but before I do, I would like to make certain that my frame is square. What would be the best method to do this?

My data pages do not go back far enough, but here is a photo of the 88up ladder frame under a truck for reference. You have "holes" on each side on the bottom in different locations. As marked in the photo, measure from A on the left to E on the right (cross ways), then measure from A on the right to E on the left, it should be the same. Do the same thing in the back finding reference points that equal on each side. As long as it "cross measures" you should be square. We use a tram gauge to do this with, but a tape measure and two people can get the same results with some effort. Second image is of a tram gauge.

Here is for an 84 3/4ton 2wd. Your wheelbase is approx 20" longer than this.
