1970 Dart Swinger FINALLY UNDERWAY

Noticed this when I was cleaning up the K frame today to POR15 it, this was under a cake of grease and looks like it was bottomed out on something during its life that left a pretty good dent in it. Kind of hard to tell from the picture but it's dented in a bit from the front lip to right over that hole, the frame itself is still straight and level.

Is this going to compromise it at all? I'd like to put a sway bar on it so I'm thinking of trying to pull it out somehow.
