lightening a Duster

I'm wondering what changes would provide the best weight loss w/$ being a consideration:

0 ditch the spare and jack!

1 Lighter wheels may be one of the easiest- does anyone have an idea of how many pounds a set of say Centerline All drags would save vs stock Rallys?

1.5 ditch the seats and use something lighter in front and kind of carpet the rear. savings???Those stockers are heavy!

2 glass hood?- probably ditch the hinges too, although I've seen some w/no springs that may be OK, but the hood has to be stronger too- so again what does history say here about weight savings w/different hoods/hinges?

3 glass bumpers- and lighter brackets too????

4 alum intakes are a must have- how many lbs are saved on average?

5 Alum heads are nice, but pricey- again, how much savings?
