Here's some of the weights. I don't have the weights for the spindles or brakes, although, that also depends on which brakes you're running, they aren't all the same (67-72 disks, 73+ disks, 9" drums, 10" drums). I have some extra 73+ disk spindles and stuff laying around so I can get those weights tomorrow if you'd like.
Stock LCA's w/tabs, bushings and pins:.......21.2 lbs
Stock UCA's (73-76) with ball joints:.......................9.8 lbs
Stock strut rods 73-76 w/bushings:.............4.8 lbs
Stock tie rods & ends:...............................4.6 lbs (these will also count 50%)
Now, that's all measured with a bathroom scale taking the average of 3 measurements, so, some variation would be expected.
