Look at a factory K and youll see most of the welds are crappy birdshit flux core looking welds and you'll realize why guys gussett them with welded in 90's. I think youll be yards ahead with a straight K that has not been compromised in a wreck.
So true they could be considered crumple zones in todays cars.
I have wrecked two mopars in my past, a 65 and a 71 both times broke my nose on the steering wheel.
