Doing a complete restoration with my son. This includes new rear rails, floors, braces, etc. Car was square with good gaps in panels before we started. Repairs are going well. Did subframe repair and have new rear rail and braces sheetmetal screwed in place. Using the attached picture is says I should be 56 5/8 from alignment hole in rail to center of #2 body mount busing on opposite side. I'm 56 5/8 from alignment hole in rail to an alignment hole in front of #2 mount...not to center of bushing. All other measurents are good. Thoughts? Am I reading this diagrahm correctly?
