I think it looks great - that is one sexy car!
I'd definitely put in amber bulbs for the rear and front turn signals. I think it just looks cheap and amateurish when I see a car with clear lenses and the turn signals blink white. It's not only annoying to other drivers, but it just makes it obvious that you installed the lenses and ruins the coolness, IMO. It's illegal to have a white bulb as a turn signal anyways - they have to be red or amber.
There is an alternative to the amber bulbs that might give you that "egg-yolk" look. APC (the ricer accessory company) and some other companies make LED bulbs that fit into your incandescent sockets. Might be a cool thing to put in there, plus you get the benefits of LED. Not too expensive either. Check out
this link. If you decide to go that route, I think you have to replace all bulbs on that circuit with the LED bulbs, however. The LED bulbs draw much less current, so if you replace your rear turn signals with the LED bulbs and leave the front ones as incandescent, your turn signals will act very funky. You'd also have to replace the front turn signals with the LED bulbs as well.
