Paul, "Adventure-Off-Road" on eBay, has a nice kit for the Delco CS130 alternator. It's a newer style, more compact and fits the Samurai engine compartment better. But they're still old enough to be easy-to-find. Current auction number is "330309255816" for the kit, but he sells one with a new alternator as well. Don't forget to upgrade the alternator charging wire to the battery. You can blow the Samurai fusible link with a high-output alternator. One plan is to leave the Samurai fusible link in place and wire around and past it, directly to the battery. This leaves the link in place for protection of the rest of the vehicle load.
