OK, it looks like it got towed with a sling back in the day like many a 70's front bumpers.

In fact thats what concerns me when it comes time to rechrome my bumpers because my 71 has that same tweak and not sure if its noticeable to the human eye or to the rechromer when off the car? I know places in the past have advertised "factory dies" when fixing bumpers but how does someone know if its really straight when restoring it. It could look great off the car but look like sh%t once installed.
