1972 Duster , starting to tear into the build

I have to do that very same repair on both fenders of my '68 Dart. I have to fix the inner braces as well so I've been a bit nervous about cutting into it and getting them right so they line up. Guess I just need to bite the bullet and start cutting.
As far as my patches I lined up an marked well but inner braces were good , If I had to do braces as well , I would have done inner brace first , drill out and remove before and spot weld in place before cutting the outer fender for patch and then line everything up before the next step
