Decided to go ahead and install the new rectifier, then buy 1 or 2 more when we get back from AZ so I can complete the external rectifier. I pulled the alternator in the snow in about 5 minutes, this snow won't let up. Anyways, I decided to beef up the voltage regulator a bit while I had it out, and nothing else to do. It came out pretty good, I trimmed the case a bit here around it to allow more airflow, and to fit the heat sink itself. It actually came out pretty good, and for $Free.50, I guess I'm doing pretty good:

Now I'm insulating the stator leads a bit more with liquid electrical tape and I'll throw it all back in the car.
