UPDATE : She made it home last night trying to keep the rpm low so as not to peg the gauge.

This morning I called her Autozone and verified that they had a dual field square back alternator in stock (had to explain in simplest terms to the dude what to look for) and a new regulator. Yep, they have them both.

She just went over and swapped 'em both at the same time in their parking lot (with lots of "Hey, you need any help?")...

Anyway, she hooked the battery back up, lit it off, and now has a steady +14v on the meter regardless of RPM and no smoke/burning smell.

Almost forgot - have to give Autozone some props; they took back and credited her for the incorrect one they gave her, no problem.

Many thanks to everybody that chimed in.
