Getting started on the fender stretch I realized how weird it would look it if the doors were completely flat, while the fenders and quarters bulged out. Thus, I decided to carry the stretch all the way through the doors.
To maintain the location and the subtle, natural curve in the upper side body line elected to make a bunch of vertical cuts and pull everything out and up. Because the width increased from the door handle to the center of the wheel opening I was able to get by just adding in a a tapered strip, without ending up with a straight line.
I mocked up a fender flair on top of the stretch but ultimately decided it looked too tacked on. I want the design to flow and like something Ford could have done, rather than something aftermarket.
With the upper part of the fenders and doors cut, I needed to bring the bottom out as well. To accomplish a little bit more of the "race car look" I decided to add fender vent behind the front wheels a la the Ferrari F40, Carrera GT, Viper, etc. Besides, doing this meant that I wouldn't have to stretch the middle of the doors
To create the smooth curved transition I used a small slip roller.
To finish off the the opening I bent a little bit of round stock on the tubing bender. This was also done to add a little bit more strength just to insure nothing buckled, or bent excessively.
I couldn't help but toss in a little bit of mesh just to see what it would look like.
