Diff and Trans Oil

[Matthew Milkevitch <mmilkevitch@yahoo.com>]

Fellow Listers;
   
  What type of gear oil are we supposed to use in the diff and trans of our 
Spits?  I've heard that GL 4 is the way to go, however I can't seem to find it 
at any of my local auto parts stores.  All I can locate is GL 5.  Any help 
would be appreciated.
   
  Thanks,
