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

Drop them to the bottom notch.
Set the front end about 3/8 lower by measuring the rocker to the floor.

Then corner balance and get an alignment.

The adjustment on the top of the rear shock is for rebound and will make the shock feel stiffer, but it does not affect ride height.
