For anyone interested, i used some cardboard as a template and cut out a profile to “fill in” the cavity and in effect make the rear portion from the diff to bar as flat as possible. Once happy with the profile simply traced it onto some Marine grade alloy sheet 1/16” (1.6mm) thick (Grade 5052 much better corrosion resistance than normal alloy).

Few pics of before / after plate fitted.

Pic 1 taken from under the diff looking towards the rear bar.

Pic 2 taken from under the diff looking towards the rear bar after plate fitted.

Pic 3 pic from rear of car.

It certainly was a lot easier than i thought as the plate is almost flat (no curvature required). I'm surprised the high end Exh companies don't offer this as part of their system. They could easily have the plates water jet / laser cut to suit their particular systems.
Now that's a proper job! Makes my half ass solution look even worse I also notice your rear bumper has a 3rd support added in the middle. I wonder when Chevy did that? My car was a 16, what year is yours?
