    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?

    I would think as long as your square with the measurement you would be ok.

    work with the 92 15/16 dim to each side.... and the 43 3/4 dims... this should prove your square and correct lentgh... the robot hole may be worng due to being a repop.... BUT.... you have many other places to check with! ;)

    When I replaced my body mounts I needed to check the frame to body square because of an issue that came up. You can see in the photo the points that I used and what my measurements were after I used a plum bob to transfer the location points to the floor.

    Thanks for all the information. I know working with after market parts can have some some error in the assembly. Passenger side frame rail should be in with the next week or two. Can get a good square check at that point. THANKS!
