Can you loosen the bolts on the base plate? You may be able to loosen those and get the unit off. Not sure if it's possible but you might be able to get to them.
I'm currently in the process of removing the accessories on that side of the engine in hopes that I can get to the base plate bolts. I can only imagine that I managed to put too much force on the stud and caused it to cross-thread inside the house. What an AMAZING design!
