Okay. Autozone has an alternator 78 Ford Fiesta, 13107 cross-referenced/matched to Duralast 55amp, lifetime warranty, $52.99 Part #13107
Advance Auto has (same cross-reference/match)#13107, Worldwide, reman w/ bosch alternator, lifetime warranty $97.77 AND they have another (same #13107) OE Quality, reman w/ bosch unit, 55amp, internal regulator, lifetime warranty $71.99
I'm getting confused.
