12SI Alternator

I bought this 94A 12SI alternator new from O'Reilly about two years ago. I've put about 7000 miles on it in that time, and it has worked flawlessly. It fits the original 67-72 brackets. I no longer need it because I switched to a CS130 alternator based on recommendations for an EFI installation.

Also included are the conversion plug adapters required to convert from an original externally regulated setup. You can pop the terminals out of your original alternator connector and pop them into the replacement connector. The larger connector plugs into the harness in place of the original voltage regulator. I don't remember where I bought the conversion adapter, but it is this type:

This alternator goes for $128.99 + $16.00 core, and the conversion plug adapters go for $22.50 + shipping.

$80 shipped.

Money order only.
