that sucks!!! I dont know whats up with those guys. I definitely wont be considering them for parts for a long time.
funny, I got a little AutoZone walking distance and a big AutoZone the next town over as well.
Ordered a New Alternator from Rockauto for $55.00 and claims 2 year roadside assistance if the part leaves you stranded.... not bad compared to $125 dollars.
My serpentine belt got thrashed as well during the good times so they had Continental Elite belt on clearance (looks like a re-branded Gator back belt) for 9 bucks, So I ordered one of those as well.
Im looking at those 2 beasts in your signature and noticing your in California, you must pay over $500 in registration a yr plus smog every other year.... I just paid $251 in registration fees for 1 truck.... gotta love that weight fee.
