You can place a hydraulic jack under the rear of the engine, remove the rear engine mount stud, then remove the large aluminum spacer .
After removing the spacer, you need to put a bevel on the edges, makes for easier installation .
Also, if you can get dry ice, it helps if you put the spacer in a container of alcohol with the dry ice added and let it sit for a while .
I cleaned up the spacer, and the mating surface on the engine case with crocus cloth, or something similar .
Used a light grease on the spacer for re-assembly .
It's still a pain, perform this with the transmission still installed, but it's less work than removing the transmission .
