No dimensional specs required! All you need are comparative measurements, in an "X" pattern, rather than straight across in three places. For example: center of left front hood hinge bolt head- to -right fender front bolt head center. Know what I mean? That will tell you if its square. If it is, your measurements will match. If you're within a quarter inch, the bolted-on body panels can probably be adjusted to compensate and correct the gaps.
Other measuring points can be used, but be warned that not everything under that hood is symmetrical. If you select asymmetrical points to measure from, it will make you think its way out of whack. Like the strut tower braces, those bolts are not in the same place side-to-side. I did try to hunt up a diagram for you (underhood unibody dimensions) with the actual specified numbers and measuring points. Did not readily find one, but its more than you need to assess the damage. You can trust me, I do this kind of thing for a living and have plenty of experience and certs to quialfy this advice.
