Repair or replace this fender (AMD)

Easy repair with a spot weld dent puller. And be fixed with barely any filler without removing it from the car. Or remove it dis assemble the fender , Straighten it, weld it back together

Here is a fender that needed to be disassembled because someone use a dent puller with punching holes. Don't let anyone punch holes to pull a dent. That is crude with today's tools that are out there.

What is the tool in the first two pics?
I've got a similar repair to do on my 73 Cuda fender. I'm going to try and pull it with the weld on pins and if that doesn't work I'll disassemble it. I have another fender that is good in that area that I can splice in as well.
