I actually like the 70s trends on classic cars....for the sake of appearance. I wouldn't do it to my car but I like seeing others.
Body modifications to 68-70 Chargers are a sacrilege. I cannot see any way that these bodies can be improved by shrinking or stretching anything. I've seen mods done to 3rd gen B bodies and am okay with it. Dave KIndig did a 67 Coronet and shortened the A pillars and to me, that was an improvement.
For me, I wanted a blend of all aspects of performance while staying as close to stock parts as I could. Dr Diff "Ford" based brakes, Tremec "Ford" based transmission. My wheels were chosen for the size and styling because I wanted good performance tires and a classic 5 spoke style.
