Snubbers are good for a door stop... It's a crutch for weak springs.
A little edit here. Those rear shackles are FINE. As long as the bushings are good and movement is free, you're good to go. Simple and effective as the movement should be linear.
That picture says weak spring to me.......and 100 percent sure if they are SS Spring.
He is trying to do it on the cheap. Pinion snubber is cheaper then new spring........... As is spring clamps for the front segment.
