67 Dart factory fuel tank

I can say that the straps were very close on mine and I didn't have a lot of extra bolt sticking through the nut, but it was installed that way in my car for better or worse and functioned. I don't for sure know if the front of the straps was in the factory location though, so that could also play into it. I think the front of the straps were just screwed into the floor pan with self tapping screws. Not sure how they are supposed to be installed from the factory.
