Alex,
The torsion bars in that 944 assembly are indeed preloaded, much MUCH moreso than a Bugs
The Haynes manuals usually excell at the disassembly of a car!
I wish I could help you more, I'm all for a challenge... (and a couple of beers)
A 36" nail bar is the only suggestion I can make tonight.
Be carefull, that thing may want to jump up or across the floor when awoken.
Perhaps the weight of a big car could be employed to hold it down somehow.
