do I need new shock absorbers?

ok, now i gotta ask a stupider question:

I'm trying to check my ride height on each side, the service manual says to measure from the lowest point of the adjusting blade to the floor. They have a pic but things arent clear to me.

would someone kindly point out what the adjusting blade or the lowest point of the adjusting blade in these pictures are. Is it the thing I have the arrow pointing to?
