Need Spacers for Icon rear shock

I think they are called misalignment spacers. Please correct me if I am wrong on this.
Bought a used Icon 3" stage 3 kit off Facebook marketplace.
The spacers on one shock were missing.
First - Am I calling them the right term?
Second - I think they can be bought from Icon for $50. Seems like a bit much. Other places to look?
Added the picture of the ones I have.

 

Yes they're called misalignments. Measure the ones you have (width, ID, etc.) and you might find a match somewhere else for cheaper. Since the Tundra uses metric bolts, and most offroad shocks use a 1/2" bolt, I think you might be hard pressed to find ones with the correct ID. Though if you can find ones with a smaller ID, you could drill them out, though you'd probably not be saving much if at all at that point (and now have a 14mm drill bit). Or find someone with a lathe.
