I have a 1969 ball joint front end with “Puma Style” adjusters. Your Link-Pin front end gets similar (but different) adjusters - See the next link:

While the Puma style look easy to adjust, I would suggest getting something like the 6253 style that, I believe, is easier to adjust than the Puma.
Adjusting mine requires getting the pressure off of the torsion bars before attempting to adjust the height. This can be tricky, at least, and a PITA at worst. ANY height change with the Pumas usually takes at least two tries before getting it right.
With the other height adjusters you can spin a bolt to adjust height up or down while the torsion bars are under tension - That seems much easier to me, to get to the same result.
As for the adjuster angles, I did what the CMC build manual told me and ran both of them them down 45°, welded in the new adjusters and adjusted them from there after I finally got full weight on the suspension (body, seats, engine, all that happy stuff). Once everything is welded back together it should be easy to eventually crank in the height you want with the car sitting on a flat surface or drive-on lift. I can’t remember if mine are set at the same final angle or different, but you can easily play with that once the adjusters are in there.
I found the cheapest COFAP oil-filled shocks I could find, I have stock-height spindles, 5X130 front disks, but mine is a widebody so I have 6” X 16” rims with 205/16 tires running 20-22 psi. It has a nice ride but is still a bit stiff, much like my old Nissan Rogue when I put it into “Sport” mode and that stiffened the suspension a little. If you want a super-soft ride, play with tire pressure in the 16 - 20 psi range. The car is quite light so you won’t need really stiff tire pressure unless you go wild on back roads 😉
