somewhere I saw a chart about body styles and aero drag. [may have been your chart]
that chart showed the 3rd gen Camaro with a relatively low COD and the 3rd gen Firebird among the lowest.
I have even considered installing a 3rd gen Firebird ft fenders and facia on my Camaro. Would doing that be worth the effort plus finding a Firebird ft and painting it?
Is the frontal drag the most critical? With rear drag less of an issue?
Hey Larry watch this video. in this case the front end was a disaster for drag but the most gains were picked up with work done on the rear of the car.
