Most folks connect the transmission to the motor while it is out of the car. Clearly this was what the ring mounting system was designed for. I didn't want to mess with shift linkage so I left the transmission in the car. This might be doing it the hard way but it wasn't that hard. I removed the bottom half of the motor mount ring and installed it to put the motor on top of. The rig required some wrestling to mate up. I borrowed the hoist from a friend.
