Can't figure out RS shock mounting hardware
 

I bought a used Sidluxe shock for a build I'm doing that came with the mointing hardware installed, not the right size for my frame but not really the point here. I'm trying to figure out exactly how it works, or at least how it's supposed to work. The shock body has thin oilite bushings that are pressed in, which one would assume is the wear point for pivoting. However, there's an aluminum bushing pressed into that solidly, so that's not a movable joint. This puts the wear surfaces between the aluminum bushing and the shoulder bolt, but also the aluminum bushing and the frame. This would require the shoulder bolt also left loose enough so the shock can pivot freely. I'd really rather not have the frame as a wear point.

I got a different style off ali that are plastic busings pressed (by hand) into the shock body and an aluminum bushing through those. This style puts the wear points between the plastic bushes and the aluminum spacer/bushing. I need to modify the parts to fit my oddball spacing but seems a much better system to have cheap replacable parts wear instead.

Anyway, what's supposed to happen with the RS stock mounting? I've looked into it and indeed the aluminum spacer/bushing is supposed to be a press fit into the oilite bushing. Seems ridiculous to not have and oilite bushing on a nonmovable joint, but also to not make the wear points on sacrificial parts. Am I missing something?

The wear is supposed to be between the thin bushings pressed into the eyelets and the bushing/spacers that press (lightly) into that.

Yeah, sometimes those are really tight and instead the wear happens between the spacers and frame. All it takes in the shock eyelet or either bushing to be even the tiniest bit out of spec for this to happen.

My couple of newer FS bikes use IGUS bushings (plastic) and they turn much easier. Also, there are needle bearing kits available for many shocks.
