These aren't body adjustable, so I'm not seeing what is so difficult.
But anyway, here is my review on them, with some other comments that should help you.

Specifically.. "Above you can see the adjustability range. Yellow is actual, green is recommended. Grey shows 20mm, what its preset at. There's my first gripe, it wasn't preset at all. Seeing that I wanted about 30mm drop, wound all units up 20mm from full low. Up and down a couple of times on the hoist to get it even."
