I have an electric fuel pump. I wanted to add an electric fan and someday I may put a radio in this car. I figured it was time to upgrade the alternator. I decided to follow Zenon's How-To.
I called up Terry Sayther Auto, and Rhett sent me the E30 alternator and required brackets.
The installation is really easy using the above mentioned instructions. The new bracket makes belt adjustments really easy.
While I had the radiator out I installed a 12" electric fan. The fan's adjustable thermostat fits nicely where the voltage regulator used to be.
