Stop in for a cup of coffee

It is the area that has the nut plates welded to it so I say no, would be pretty easy, I have a nutsert tool that goes to 3/8. Hopefully over the winter when I pull the motor again to do the engine bay and re paint it again with the fender skirts.
Where are there any welded on fender? I thought they were all the slip on U-nuts. And most go on the car and bolt through the fender...
