Lighten up my race car

71 Duster dash is pretty gutted I need to remove old wiring. Bench seat no back seat steel tubs have all stock glass. Wilwood front discs made a big difference in weight glass lift off hood glass front bumper. I recently added some weight as I added tti 3 inch x pipe exhaust and ultra flo muffler see what happens I may go back to the bullets. I am now looking for more weight to take out. That's why Im interested in this thread I have thought about lexan and glass doors and front end.
