Are Z3 fenders gay?

I need a new pass. side fender and I saw the ones you were talking about on ebay. I was considering fiberglass to save weight on the front end (any ideas on how much weight I might loose) I was considering those and then bondoing up the gills but then I figured they would weigh just as much as steel ones. If you get those and do a fiberglass patch...lemme know how it turns out and how much lighter they are than stock.
 
don't the Z3's for stangs also have two more little scoops/gills where the rear of the fender meets the door? Just something to think about if you are gonna do Oink's idea, which is actually a pretty good idea, I'm surprised I didn't think of that. I mean you will have prep work most likely anyway, so filling them in wouldn't be too tough I don't think.
