Anyone come across any vibration isolation mounts...those are a piece of cylindrical rubber, maybe 20 cm or so in diameter and can be 10 to 20 cm in length, with a threaded bolt piece on each end. I need to mount an AC condenser unit on my bedroom wall and want the sucker really, really isolated so I don't hear or feel it. I have done this before in another country where these were plentiful, but am having a challenge finding them here. Any leads would be greatly appreciated. ett

They are similar to engine mounts. Maybe you could try an automotive parts supplier.
