Front bumper on a 65 dart

switch to an aluminum master cylinder and if you have power steering dump it and get manual steering. Anything aluminum that you can put on the engine to replace cast iron will of course help. If you're using your stock good for now, cut off the bracing underneath, but if you do that you need to weaken your torsion hood springs by heating them up somewhat with a torch. Use as small of a radiator as you can get away with. Remove the splash guards from inside the fenders. A bench seat is lighter than Factory bucket seats. or go with some racing seats. Scrape off any undercoating that you can find. Find an aluminum Driveshaft in a junkyard and have it made to fit your car. Remove the headliner and the carpet and all the jute backing. I think somebody already mention to replaced the heavy steel bumper brackets with some lightweight aluminum brackets or with some pipe hanging material. What else??
