Remember quality back in the day wasn't high priority. Look at some "cold fusion" welds on the uni-body. Every car was different. That being said it's not that big a deal to get the alignment pretty decent. Want it perfect? Weld some tig rod to the edge and then do some metal finishing. All personal taste, just like paint finish. The gap on the car shown could definitely be tightened up with nothing more than some adjustment and maybe a little hole elongation. Personally I like 'em slick. Even my racecar.
