the alternator in my 79 is about to die.  I have called around to get
price quotes on rebuilt ones.  Pep Boys has one with a lifetime
guarantee for $62.  It is not Bosch, though.  Another place has a 
Bosch one for $131 plus $30 core charge.  I then called to get a quote
on a used one from a VW mechanic.  I told him about the Pep Boys
product and what it cost, and he basically screamed saying "They
just keep breaking and cause harm to the fuel injection system."
   
Anybody have experience with the off brand alternators with a lifetime
warranty?

Thanks, 
Paul
