I think the thing to do would be to have the engine in gear to lock up the 
input shaft.  This would force the two wheels to try to move in opposite 
directions.  As you know, the std dif will move quite freely.  I've never 
done it, but I would expect the LSD to feel much different.

This sounds like a very good way to test to me.  OTOH, it might just be that 
the serial number of an LSD equipped tranny has a different prefix.  After 
all, they had to be able to keep track of them at the factory, too.

Has ANYBODY here ever actually touched one of these?  Or had a friend who did?
Friends of a friend don't count.
