I've done mine. Jack the car up and support with jack stands. Remove the wheels (had to include that). Then place a floor jack under the spring perch and lift enough to remove the rear shackle bolt. Drop the backs of the springs before taking the front eye brackets off. There should be three bolts on each eye bracket. If yours are welded, it's because a PO probably ground off or cut a bolt at some time and couldn't get a new captive nut in the frame rail. The bushings in the rear should just slip into the end of the spring. I'm not sure about the rear sway bar. I haven't put one on my 69 (yet).
