As a point of reference this is a '92 400e w/V8. Per my previous posting below the Idler Arm Bushing / Repair Kit was not rocket science. What I didn't realize at the time of writing is that the bushing came out separately from the rubber mounting sleeve on top, so perhaps that would have afforded some of the clearance necessary to get past the exhaust.
In any case I did follow my plan as below - the only real hangup was that having pressed in the top bushing the bolt length was just shy of what was needed to get the nut onto the bottom with the bottom bushing in place, ready to seat it properly. A floor jack angled with some wood blocks and topped with a large socket made this possible, if not easy.
Seated it far enough in place to get the nut on and completely seat it with the old locking nut. Removed that and replaced with the new locking nut that I torqued to spec. Job Done

Assembly would be the opposite with the bolt in-place as the top bushing is installed. My plan is to use the old nut and using the idler bolt & hardware itself with some heavy washers on the bottom to press first the top bushing into position, then a rubber mallet for the bottom bushing and that same setup to press the bushings as a pair into position - I can see no other way to do this, shy of removing the exhaust system, and there's no mention of the need to do this in the MB shop manual.
Weather was turning for the worse, so I just put everything back together for now. I'll try to work on this in the next couple of days and post on any developments.
