Alternators

[Vincent Gelinas]

Hi, all!

What's everyone's opinion of the Duralast alternators from Autozone?  The
one I'm looking at (AZ p/n:13430 comes with a lifetime warranty and lists
for about 154.00.  Or, should I go for the Bosch unit (Bosch p/n:AL0715X) for
almost 200 from JC Whitney with a 1 yr warranty?

Third, has anyone ever made an alternator cover so oil/crap doesn't get
on/in it?  My alternator is cooled by an air duct, so I'm not worried about
overheating it too much.

Thanks in advance,

Vincent
