That's my opinion but my panel beater says he measured everything using the autorobot chassis machine. I said to him it might be as much as 20 mm out and he says impossible "maybe 1mm but 20 mm is huge, no way" he said.
It also feels like if I push the left side forward the diff mount may line up. I have a day of measuring this weekend I think.
My panelbeater did do the typical rust repair work they all seem to need in the rear legs but he never had to move the beam mounting holes or the diff mounting holes. He also measured the car after the work was done.
It would be good to get some dimensions off other cars relating to the positions in my photos if possible.
