Underhood dimensions 71 Swinger
I saw in your thread you've got a car that was hit and is no longer square. In my opinion, you should be using frame dimensions from the factory to make your checks. Comparing the locations of the fender bolts isn't a great reference IMHO, there's a lot of adjustment to be had there. The body measurements on these cars are all over the place, even on cars that are straight. A 1/4" of variation was factory tolerance on the suspension points, let alone the body points.
These are the factory frame dimensions for a '71 Dart, same for a '70. This is what I would check. The fender bolt locations I'd be a lot less concerned about unless the fender wouldn't bolt up or align with the hood. But again, there's a ton of adjustment there. As long as the rails are straight, the rest is just getting the gaps to line up. I'm not saying a reference isn't useful, but, I wouldn't count the measurements off another A-body as gospel, even if they were off a straight car. Guidelines maybe.
