I was looking at getting the clutched pulley for my alternator but the cost of the pulley is $116 (cheapest I can find). Is there an alternator from a newer model jetta with the clutched pulley already on it that can bolt directly into my 1994 1.9 diesel jetta? I would just go to the auto junk yard to find one.
TDIs have the clutched pulley but I believe the mounts are different, and I don't think they have the W-terminal either, since the TDI tach is driven from the ECU. And, at least around here, TDIs are too new to show up in a junkyard.

Perhaps ask Brian at Roseland Technical Services about the pulley... his site shows one for $60, although it might not be the exact one you're after.

crap, he has the wrong pulley. I need the one that ends in 119 AA
I ordered mine from a place called autopartseh! I think it was about $80.

He's able to get just about any OEM VW part... might be worth an email.
