Any tips on how to replace the isolators on the left side of the powershaft?

I made a short screw jack to lift the powershaft (see the attached pictures). One of the engine/powershaft support bolts was broke off below the casting so I pushed a copper sleeve in the hole and welded a nut to extract the broken bolt. Much faster than pulling the powershaft...
