NE1 have the Body alignment dimension drawing

May want to have the front sheet metal handy before having any straightening done.

On a modern car you can pull to spec and have everything fit 99% of the time, but you are also pulling to within a millimeter or two.

Old cars, old spec sheets, wide production tolerances, best to pull and fit the parts, and pull some more and pull again until it is not only within spec but will also accept the panels without shimming the hell out of everything and still being left with bad gaps, like they were from the factory.
