Stop in for a cup of coffee

Obviously I do not know your shop layout, but no way you can lift body off and remove from bottom? Maybe some creative rigging? Alternatively rent some kind of equipment to lift it off if you do not have any way to rig? You are a smart guy so I am guessing you got it sorted out but that just sounds like a sucky deal all way around?
That is how I installed everything. So there is that option...
