      69 GM A body frame question

      Can anyone clarify which of the holes in the frame are the holes referenced on the sheet for the dimensions? I was doing some work last night and there was some discussion that the hole I was using for reference is NOT the hole that is shown on the sheet. I have a 5/8" diam bar through the set of holes that is being used, but not I am skeptical as the sketch is not specific.

      Which dimension are you referring to exactly? There are two 5/8" holes that come up from the bottom of the frame and are used for body alignment.

      The forward hole that is the datum reference for the body mount dimensions, the hole shown in this chart. Am I referencing the correct hole in the frame as I am showing in the first picture?Name:  unnamed (1).jpg

      Yes it's the bigger 3/4" hole, or yes it's the hole with the bar placed through it in the picture I took?

      That is the "problem" well...that is the debate. I was under the impression that the hole with the piece of bar stock through it is the reference hole, but a fellow "car enthusiast" has it that the large circled hole is the proper hole for reference. I really need to get this clarified, as it creates a rather large problem if I get it wrong.
