I think the Mach 1 sail panels would look killer on there and would match up nicely with the bullitt side scoops.

I think the angular look would fit in really well with your other mods
IMO the way your car looks now, the scoops seem to point in the direction of the sail panel but the sail panel doesn't seem to match up. Looks weird, you know? With the Bullitt/Mach 1 panel, the scoop angle and the panel angle match up nicely as seen in the picture.
