Very interested in your project - subscribed !
You are very lucky to have one of the most easily aero-modified cars on this site.
Stock, your car had a drag coefficient of around .45 , .47 - (or even higher.)
I'm guessing at that based on the fact that a 1970 - 1973 Camaro had a Cd of .497 !
With two simple mods, you can drop the Cd down to
point 20 !
To put that into perspective, that would be like driving around with a parachute open behind your car, and then suddenly taking it off.
Your car would be sleeker than any car on the road today - yes even the Tesla ( which is .24 ), yet would still retain its' original look.
Hot Rod magazine did an actual test using your body style ( or very similar shaped body style - a 1980 Camaro ) in a wind tunnel.
No boat tail, no wheel skirts, and a barn door flat front end air dam, yet achieved an amazing .201 in the wind tunnel !
So needless to say this could have a
wonderful effect on fuel economy -( as well as top speed ! )
