Years ago I was going to do a alternator conversion in my TR3. However I wanted to keep that original look and kept me from doing it. I was looking for something on Ebay and came across this set up. Any one do this? I would want to keep the original Voltage regulator in tacked too and run everything thru it but I'm sure it would have to be gutted since it has it's own internal regulator. A little on the pricey side too but seems very easy install. I emailed the seller if the original pulley will fit on it but no reply in the last 3 days.
