The problem left w/ both fenders is that in center of fender say 4" from top body line and 4" from bottom body line fenders do not line up w/ door panel curve. I used a straight edge and top and body of straight edge laid on door touches front fender on top and bottom. Its the center that's a little low all the way to emblem holes. I am thinking of taking off fender and making a few relief cuts in back and edge then putting fender back on and give a couple of gentle pulls w/ slide hammer. I'll sent a few pics. after ready your discussion it seems normal to cut weld and move to get what you want.
Below are some drawings I made up years ago when I had to cut in relief cuts on the inner structure of the fenders for my 74 Spirit of America Nova.
I had tried with brute force trying to get the right curvature in it but I was worried about applying too much pressure and then either denting or damaging the skin or over bending it.
What I also experienced was after I got the middle to curve outward more is it also affected the bottom portion as not the bottom lip bent upward. For this I then had to slice open the inner structure, open the angle or cut to get things parallel again.
#1 is looking forward against the back edge of the fender
#2 are the 2 relief cuts in the inner structure only
#3 is the middle bowed out more and that slice closed up in the middle of the fender but then notice how it puts a different angle on the bottom lip
#4 is with the bottom slice opened up to get the bottom lip square again
#5 is a layover of it before then after
On mine after I had the slices or cuts in the inner structure I was able to get the curvature right and then opened the door and got in there with my wire feed welder and tacked across the cuts to stabilize it and not have it move on me with taking it off of the car.
Here is the album I have on some bodywork where I was using a paint stick to see how my panel to panel levels were:
