Well, Otto's acting like he needs a voltage regulator, but my question is this: What's the difference between the Bosch 0.192.062.007 and 1.197.311.090? More importantly, why should I pay $35 for the .007 and only $12 for the .090? They both say they will fit my alternator.

Anybody had any experience with these?

Oh yeah, almost forgot: Any tricks to give daughter #2 that will have to limp this beast home (100 miles) with a psycho regulator? (Lights go dim, then atomic.) I'd like to avoid replacing any dash lights, or worse, battery if possible...
