Yeah, definitely stay away from one peice projectors. Not only do they not fit worth crap, but they're horrible quality and they don't give out any light whatsoever...trust me, I thought they looked cool like you, but they're absolute crap.
Just keep in mind when you're buying lights that the SMOKED LENSES block some of the light. It's like window tint, so you're not gonna get as much light output. There's also some with UTLRA CLEAR LENSES and a BLACK HOUSING that give the same look, but put out more light. That's what I would try to get. They make some called "Black Beauty" that work pretty good I think. Just do a search for Black Beauty and you'll get some opinions that way.
Those from American Muscle look good. Dark lights on a yellow car look great. Keep in mind though that your'e not gonna have much light outta those either cuz they have a smoked lense instead of a clear one. You'll be find if you put in HIDs, but that's the only way you'll get any light.
Here's some that have a black housing, but a clear lens and refletor so you'll get the dark look, but still get good light too. I can't find their corner light that matches, but I'm sure they make it or there's other companies that carry these.

I have the ultra clear version of those and they work great.
And they're HID compatable (at least that's what the box said).
