Hello captaintobeys, You will want to get a single groove pulley made for a 3G alternator. They are commonly available. As far as the external regualtor is concerned, I used an upgrade kit from P A Performance that retained all of the functionality of the "gen" light and was very easy to install. The part number of the upgrade kit is 462802C. You will find that this is a very reliable and safe way to upgrade your Pantera's old electrical system.
