LCA Indexing and Torsion Bar

I've seen worse. The finger like thingy in the lower arm has a dimple in it where the nose of that adjust bolt should be. The female threaded adjust block floats. One members adjust bolt went to one side and ruined the dimple and finger.
Even with OEM parts, you can't just crawl under the car with and change its ride heigth. The suspnsion has to be unloaded. Jack to unload, adjust, lower, jounce, check, redo.
And that's why coil springs were much simpler for other brands, but... those owners needed spring blocks to stiffen or a torch to lessen their springs.
Torsion bars provide a screw adjust but it's not as simple as as some beleive.
