frame issue question

Today while working on the front end of my 73 Duster, after removing fenders and bumper I found this issue with my frame.







It appears to have affected the area just in front of where the k frame bolts in on the passenger side. I am wondering if I should cut it out and replace the segment along with the radiator support which is also bent on the driver side or try and have it straightened. Anyone deal with anything similar out there? Any suggestions?
