Simple way to replace inner wheel well lip and Quarter panel install tips!

Thanks for taking the time to do this. I've never done any body work or rust repair on a car. I'm interested to try and tackle some of this work myself. I spent most of my working career as a HD Equipment Mechanic and certified welder, so most of my welding experience is on much thicker metal. Warpage is my biggest fear in trying to do this type of repair.
My '67 Dart is starting to show some rust bubbles in the paint in the wheel lip area.
I'm assuming you used that wheel lip material because you couldn't get the replacement patch panels that you needed?
I looking forward to the next segment.
