Yeah, I'll just leave the headlights alone for now. A small airdam and partial undertray (which I'm working on now) should have more noticeable results anyway.
And I got my MPGuino in the mail today! Hooray! Now comes the task of figuring out the wiring without a service manual. I'll give it a shot, and I'll definitely be reading the relevant threads on this forum.
And on a side note, when I still had only the rear wheel skirts done, we were driving through Missoula and a random guy shouted out of his vehicle window, "Hey! Sweeeeet!" and gave me a big thumbs up. I guess he liked the covers. I'm now not sure I'd want the attention a full boat tail would bring.
