1995 E320 wagon

I've got the new rubber shock mounts for the load leveling shocks. any special tricks for changing these guys out? can I just jack up the car, unscrew the bolt from inside and have the rear shock free enough to take off the old rubber and put in new ones? or do I have to remove the 2 screws on the bottom too? Its looking like there is enough slack in the oil line to allow me to swap out the parts with having to mess with it (kinda like calipers). what say you?

I got it guys. super simple, I just released the 13mm bold from inside the cabin and presto. so while I replaced both rubber bushings, it turns out that wasn't the cause of the clunk I was hearing, but at least I've got new mounts and they were cheap.

...now on to diagnose which of the arms is the problem...
