Odd they would assume it was disabled when the struts are still there, accumulators, hoses, oil circulating, etc. As long as you are confident, that is good.
Since I started peeking under the skirts of junkyard 560s (they are not common here) and SLS W126s, each one has had a worn out SLS link out back. Mine included as well as yours. I would prefer one from Heim joints too.
The pump is pretty easy to rebuild and the kit is about $50. I have some pictures if you are interested. The high side hose is a serious punch in the face to route.
Subframe bushings are a PITA on these. A rear diff mount helps big time and is easy to do.
