Weight saving ? with a 543 " motor I wouldn't worry too much about weight. Anyway , outside of fiberglass panels you could strip all the paint off the front sheet metal & doors and send them out to the acid dippers. Also you can move the wheelbase on the car 1" , its like taking off a couple hundred lbs. off the nose...Not to hard to do, a little drilling moving this and that some welding, and presto great weight transfer..and a set of Cal-Trac's with a adjustable rear shocks. I also used '67 Valiant front drum brake set-up, (real small brakes/spindles, 23lbs per side lighter) but don't expect to stop very good. That's if you want to keep it relatively stock looking , but C-P would probably put a 4-link in it with big tubs....(Now your going to make me want to go racing again).....
