1/2 ton GMT400 SUV rear sway bar.
From the SUV you'll need...
~The frame brackets, along with the bolts & the specific nuts that fit inside of the frame. Those have a tab on them which hits up on the inner frame rails to prevent them from spinning. Can't get a wrench in there to hold 'em.
~Some 3" H/D extended length muffler clamps. Regular ones are shorter & the steel bar is a lighter gauge.
~New grease-able brackets/shells with urethane bushings from any parts store for cheap. (-$20.00?)
Do this on level ground.
The muffler clamps go in between the 2 plates of the shock mounts on the diff. One will face forward, the other back.
Slide that pressed & bent muffler clamp piece with the holes over the ends of the bent part.
IIRC the urethane bushings are split so they can be wrestled onto the bar. If not, gotta slide 'em on over the ends of the bar. Assemble the uprights & frame brackets onto the bar.
Bolt the assembly onto the muffler clamps. Fairly snug, but still loose enough so that they can be shifted around on the diff. The bolts have to be holding both the clamp & the bushing shells all with the one nut. Don't forget a washer.
Now you need a 3rd. hand. Someone to help get that bar horizontal to the ground & square to the frame. Tighten those clamps a bit.
With the weight of the vehicle on the tires, get a hold of that upright/bracket/sway bar assembly. While holding those uprights as perpendicular as possible (Straight up!) to the ground, trace around the outside of the bracket. Mark the one hole that's not blocked by the upright.
Drop it down, remove the uprights from the brackets & mark the second hole. Drill holes.
Next, bolt the bracket to the frame using the donor's bolts & those specific nuts. Can't do that with the uprights attached to the brackets. No way to get any tool in there.
Mount up the brackets followed by installing the upright. Check to see whether the clamps have shifted & that the bar is still horizontal & square & that the uprights are still perpendicular. Adjust if needed. If it's all good, give everything a final snugging up.
I had a bit of a prob getting those uprights exactly right. Rather than re-drill those holes in the frame, a bit of a PitA, I slotted the holes in the frame brackets so I could adjust them to be just right.
One one side, there is big rivet in the frame right where the bracket wants to be. Instead of messing with the rivet, I just drilled a pocket into the bracket with a large drill bit for the rivet to sit inside.
Altogether, it took me the better part of 2 hours to do the first install of one of these.
The drilling of the holes in the frame took a while. On my back in the driveway. Hot shards of drilled frame metal falling! Yeow! Lol!
Aftermarket S/B manufacturers use the same method with the U-bolts/Muffler clamps to install their bars on vehicles not factory equipped with.
Since the pic, I installed some new urethane bushings in the end links.

These were around $20. I used the black ones, though.
After I did the rear bar install, swapped all the front sway bar bushings with urethane, too.
