You can move the driver's side axle out of the way and fiddle the
alternator through the small opening that affords.  Alternately, you
can put a jack under the engine, then remove the left motor mount cross
bolt (in front of the timing cover) and the upper bolt on the front
engine strut (not quite a motor mount) and lower the engine a few
inches to gain clearance.

If your friend considers metric tools to be special, then you may want
to seek other help.  Perhaps he was talking about a 32mm axle nut
socket?  You can get a Calvan, KD, or equivalent deep axle nut socket
at Autozone type stores for about $15.  They are very good quality for
the money and USA made.
