JC I can confirm that the alternator in your garage is exactly what I have. So thanks for the offer, but I've got a brand new one here. I'm beginning to think I just fell into the trap of removing this thing too quickly, and not paying attention to how it attached. But I swear the pulleys don't line up even if I can finnagel a way to put this alternator back in. ________________________________ From: John Christensen <johncgg@xxxxxxxxx> To: elky@xxxxxxxxxxxxx Sent: Wed, November 3, 2010 8:59:17 PM Subject: [elky] Re: Alternator problem = Elky killer Check these pictures out Saul and let me know if this looks like it could replace your old one.
