Lets talk about fiber glass body parts.

This winter I'm thinking about lightening the weight of my Dart. It currently weighs 3245 with me in it. I was thinking about replacing with fiberglass hood, bumpers, and front fenders. I'm just worried about the look. I don't want it to look flimsy. I prefer a stock look with the benefits of less weight. I'm thinking I can save about 150lbs by doing this. What are your thoughts?
