When I did motor mounts and new engine shocks, I also got new shock mounts. The shock mounts that are on the top side of the engine shocks have a rubber component in their center that goes bad over time - so its a good idea if you're going to the trouble of getting new engine shocks to also do the top shock mount brackets. The bottom of the engine shock is a more conventional bushing assembly like an old-time suspension shock absorber.

I'm speaking of the '82 300D - which I hope is helpful to you in the SDL.
