Drill out all pinch welds (aboout 100) as you get into it it will become easier to understand what you need to do. Be sure to test fit your suspension before all final welds are made.
I like to support from the bumper support or stabilizer support. Remove suspension carfully. Replace all suspension bushes when done prior to refitting.
I reinforce the pinch welded suspension pick up points with a bead of weld all the way around to prevent future fatique and thus rust. Real epoxy primer, body shutz, more primer and good paint are a must. I also zinc primer the cavities between everthing as it goes together. Don't use weld thru primer as it sucks. Zinc may burn but it will migrate to bare steel on its own later.. Good luck.
