Weight savings
Norm your thinking of the door beems. They are pretty heavy from what I hear. Not sure what the first year they used them was but I think it was 72. You could take them out and no one would know.
Back seat, light front seats are a good way to start.
I tossed my heater and radio, Extra carpet padding is gone, Battery in the trunk, plastic fuel cell, small starter. If you cant remove it all together try moving it back as far as you can.
