Control arm hits the frame

Hahaha - you are great! :-)

The strut rod bushings have also been replaced (see picture above) ;-)

I nearly was 100% sure that the adjuster tab was not set in the right position. But when I released the tension with the adjuster bolt completely and pulled the torsion bar out it came down all the way and was even with the LCA. My suggestion was that the adjuster tab won't go all it`s way down and is set to high - but it wasn`t.

I really have no clue why the tab keeps hiting the frame :-( And I have also no idea where that noise is coming from when I hit a gully or bumps.

A mate swung the car up and down while I was laying under it but I couldn't see that the tab is scratching or hiting the frame. You also can't hear a noise then. I am sure you'd hear something when the tab hits the frame.

Since I just recently was under my own car with all that apart I know exactly what you mean by your descriptions.
Do check the other side as mentioned above, because I was so busy being a smartass I didn't think about the possibility of the K frame being off to one side. (That's possible) (of course as mentioned above, bent or broken control arm pivot pin could do it also)
As far as the noise when you hit a bump, you might chk both ends of the shocks also, as a loose mount or missing grommet can make a hell of a noise when they move.

DOH, just saw your post.

William was asking about side to side movement of the K frame, not ride height.
Chk those big bolts holding the K frame in.
Since you said the mark looked older on the other side, the whole K frame could be shifting side to side.
