Do I add a spoiler up to meet the line? Like a wickerbill? At what angle?
Or do I go back to meet the line? And at what angle? The last of my trunk lid rolls down quite a bit.

CAR and DRIVER experimented with airdams and spoilers on a Ford Pinto,a Dodge Van, and a Datsun 240-Z.
A wrap-around airdam would help keep air from under the Chevelle,cutting drag and front lift (my '67 El Camino was terrifying at an indicated 120-mph!)
A rear spoiler,tilted up at no more than 30-degrees above horizontal,just touching the 'template's' imaginary contour might be a good first approximation.Theoretically,a straight- back foil, ala NHRA/Bonneville,would be lower drag,but it would have to be 'soft' like the rubber-edged Porsche 911 Carrera 'whale-tail' employed, to protect pedestrians.
Rocker panel extensions like on the Trans AM Firebird, even with the bottom of your airdam would help.
Forget the splitter.It will only create drag.
An electric cooling fan if you don't already have one. Keep the fan shroud.
Block all the grille except for the actual perimeter footprint of the radiator.
The headlight recesses could be covered with Plex/Lexan.
MOON covers are a known drag reducer.
