Help with rear shocks and adjustment please Options

[Wyvern]

I have these shocks on my 73 1.7
They seem "ok" but just want to understand their adjustment.

From my research they are Koni "Reds"

Question 1 ... My car rides high (I think so)
Measuring the "donuts" as what I understand is the preferred method I am at 6 1/2" on the rear and 5 1/2 at the front.
Am I correct that the clip on the spring perch can be moved down to correct rear ride height ? ... then adjust the front torsion bars (yes ,,, then alignment)
I thought they had 5 grooves. Looks like (I am in 2nd from the top / highest.
What height should I be targeting ?

Question 2 ... I have found 3 different instructions on adjusting the compression / rebound . any help with the correct way and info ?

Thanks

Thanks "Luke" ... I saw your post after removing the shocks and setting the clip at the lowest on that collar.

That dropped the rear just over 1/2 an inch. No collar would only give me maybe 1/4" more.
The stance is "better" . I researched a bit more and there was discussion about drawing a string along the top of the rocker and noting where that line would cross the center of the hub. (goal mentioned was for that string to intersect both front and rear hub centers.

Using that system ... I look to be 1" low on the front & 1" high on the back. to my eye that sounds where I want to go . So I still want to drop the rear 1" (even a bit more and I can balance it using front torsion bar adjustment.

I think that I must have newer stock rear springs and am tempted to go to some 140s for the rear ... How much drop would that actually give me is the question ?

Here is my front
