GM 1 Wire Alternator Self Exciting 63 Amp New Delco one wire 10SI SBC BBC Replacement for Chevy 350 GM Ford 334-2614 7127SEN

Most folks doing GM alt swaps use the been around a million years 10si style. Your CS130 also has the B+ sticking out the top. https://www.amazon.com/dp/B0CPY6FH28 I did find this too, someone also says it's a GM alternator and looks just like OPs. plug and B+ look to be in the same placement. I think the OEM Suzuki one has the B+ also sticking out the side/top not out the back. https://www.reddit.com/r/SuzukiSamurai/comments/190qj94/help_wanted_is_this_alternator_oem/
