Jrlegacy23's 72 Dart Build, pro-touring style

My plan is Hotchkis rear leafs, 1" torsion bars, 4 wheel disc brakes, lowered some (unknown how much), Mini tub with 17"x10 or 10.5" wide rear wheels, 4.10 gears limited slip. Most of the parts I already have, but I still need some more parts. I am trying to keep it pretty sleek and sharp, with a lower profile look.
For the lower profile look, I have been looking at an 82-92 Firebird spoiler. It is about the same width as the go-wings. I think it will compliment the Dart body nicely.
