These cars have "issues" -- they're not exactly spring chickens... they've had a rough life... The point is - that you either have to get the body back to where it should be - or you have to modify things to get all of this to line up and be square and the wheelbase to be right. Whatever course that takes is a matter of skill and pocketbook... etc.
When I did my brother in laws Camaro - it had taken a hit on the driver side... so much so that I had to pie cut the area where the steering wheel goes thru the firewall... and I had to make a "spacer" to take up the area under the floor between the floor and the sub mount. We didn't have another way to fix this "alignment" issue. We made it work and the car drives perfectly. And his gaps are perfect. The key is to have accurate measurements so that you can "fix" the issue and know what you're doing. You can fix anything if you know where you need to be when you're finished.
Check out this "spacer" I had to make for the driver side! I milled it to the .001 of an inch... just because... there was really no reason to get that close other than I just like using some of my tools. HAHAHAHAHAHAHAHA
