Weight savings
now your on the right track norm. one of the first things i did years ago was loose the inner brackets on my car (they weighed more than the outer ones) then i windowed out the brackets for further savings. a little here and a little there will get you down on weight. torsion bars are a good place to look for weight transfer and weight savings. look for 72-older slant six without air bars. they were the smallest you could get without shelling out for the new drag bars. does the car have sway bar? remove it, and all the brackets. swap the arms out for ones without the tabs on them. the k-frame idea is good, but my experience is that when boxing back in, you sometimes add weight too, but 80% of the time you'll loose weight. a good place there is the seams where the to halves are welded. cut the seams, weld it all together. a hole saw here will work too.
