365 Transaxle leak

[Dilkris]

..... To get to here, I disconnected the battery and gas line since I didn’t know how much travel they would tolerate.  I also partially drained the coolant as well.  I blocked under the transaxle for support and lifted the body after disconnecting the shocks lower mounts....

I am fascinated by this - at least you found out what was involved in removing the rear cover of the 365 box  BUT I do not understand why you had to lift the body - or are you referring to the chassis and body as one? Also you surely must have had to disconnect the coolant pipes from the front of the engine and loosened the engine mounts to be able to tilt the rear of the transaxle by what appears to be 6" plus (150mm plus). Or did you drop the engine with it?
Finally your car appears to be on a four post lift.... is it?

I didn't state clearly what my process was and I apologize.  When I said "raise the body"' I should have said raise the suspension with body attached.  Disconnecting the lower shock mounts allowed the chassis and body to go up while the frame and motor/transaxle remained stationary, giving me vertical clearance  between the frame cross member and the cover.  I used a chain fall hung from the ceiling joists to raise the chassis and you can see the yellow sling wrapped around the frame cross member.  I went up as high as I could until the transaxle began to rise .  A couple more inches would have been nice, allowing a clear shot off and on for the cover but this is as high as I could go.
I really didn't want to rotate the motor on its mounts because that would have caused me to disconnect the rubber coolant hoses between the motor and metal tubes.  The Lotus does not present a convenient place to drain the system and I'm using waterless coolant at about $35/gallon, so I try to conserve every drop.  Separately, I'm looking at installing a drain plug in the small hose that connects to the passenger side coolant pipe to make this easier.   I did partially drain the coolant in case something became disconnected unexpectedly.  My thought was if I could gain access in this mode terrific.  If not than I would have begin to loosen motor mounts. 
Yes, the car is on a four post lift.  I debated between this and a two post and concluded this was better for my situation, mostly because the four poster is mobile while the two is anchored to the concrete.
I hope that clarifies things but if not, just let me know.
