Capturing a piece of early 70s Trans Am mojo...what can be done?
I've been trying to capture that same essence since I bought my Cuda in 1993.
I think you've done a great job already. The minilites, spoilers and gumball on the door really have an impact.
Flares are always a Trans Am trait. But your paint looks nice, I wouldn't have the heart to do it.
My personal preference would be a twin 1974 style snorkel scoop because it reminds me of the T/A scoop more. And less aero impact. That's just me, I still think your scoop is period and fits.
Maybe a race inspired all-business dash cluster would be a plus. Something inspired from the GT-350-R model. Black "camera-case", textured or wrinkled finish. No shiny stuff except for the gauge rings.
You would be able to ditch the cluttered look of the 3 gauge near your knees too.
