Capturing a piece of early 70s Trans Am mojo...what can be done?

That's where I've been trying to take mine (sorry no other pics at the moment besides my avatar). Granted the 18" wheels aren't exactly accurate but I'm building my car for performance first, looks second and needed good selection of modern performance tires. I've done a good bit of suspension mods (all retaining the factory setup, no silly coilover conversions) all for the sake of handling and high-speed performance. Needs bigger brakes (and rear discs) and good shocks but the saddest part is I'm still running a 904 auto trans :( I do have a long-term goal of swapping in a TKX or T56 overdrive manual.

I currently have the (incorrect for my car) dual-snorkel scoop and really want to add a front chin spoiler/splitter and a rear ducktail spoiler. @MRGTX where did you get yours? That thing looks fan-frickin-tastic! Same goes for the chin spoiler, slightly shorter than what I'd want but similar style.
