Unfortunately, you won't find any pre-made repair panels for an Aero.
As Mark indicated, there are some NOS replacement panels still in existence, but they are quite difficult to come by. I have never encountered any repair panels for the floor.
Anything you'll need will have to be made. I found a local rent a garage joint that would let you use tools for a monthly membership fee. They had a fab shop with shears, brakes, bead rollers and the like. I used those facilities to make repair panels for my car. You don't necessarily need something as specialized as a Pullmax to make body panels. I made paper templates off the car and transferred to new sheet metal.
Just a suggestion. You may or may not have something like that locally, or be so inclined to attempt.
Best of luck on your project.
