Wow, never thought about that. I have seen it done (on a lift) on that show Graveyard Cars. However, I have a pretty small 1 car garage to work in and I don't think I will have enough room to do that. Ill look into it this week. Also, I have a plug for the transmission tail shaft.
You can use plastic cups (made for this purpose) for the tail shaft, instead of using a slip joint. They do not fall out of get in the way. I have a set for different size openings.
