What does # N 013 319 1 do for a living?  (item 11 in my drawing).

My workshop section (000.5147.60.00) also doesn't indicate any
difference - but it's dated September 1987, so this is no great
surprise.  My local dealership says the ALZ differential is a "return
to factory" part.  Tim at The Parts Department can't find any workshop
information specific to the ALZ.

There was never a TORSEN rear for the ur-quattro.
