<VV> Drive Train Removal & Installation

[Shelrockbored at aol.com]

I have watched and helped a friend remove the drive train from both early  
and late models.  I have also helped him reinstall the drive train on both  
models.  I feel that I can do it myself with some help (I would never try  
this alone).  My friend uses a tranny jack with the Corvair  engine power 
train cradle bolted to it.
 
Question:
    
        What kind of equipment is  available to effect this?
                Obviously  one needs something a little heftier than a 
floor jack.
                        What  is suitable?
        I have been trying to find  the power train/engine cradle (GM tool 
J-7894). 
                    Is  this still available?
                    What  can be used in its place?
 
Still only in the discussion stage but would like to hear  
ideas/thoughts/comments on this.
