Everything works as it should and I bought an open box one for cheap. Power Master is 👍 I drive an ‘84 Camaro Z28 with a 305 Review: Powermaster alternator works, accomodate double pully switch over for Grand Wagoneers with AC! - Powermaster 7294 accepts double pully switch over from origional alternator on Jeep Grand Wagoneers (spindle is long enough). Double pully is necessary for Grand Wagoneers with AC (at least 86-91)! Dozens of alternators sold at autoparts stores and on line say they "fit" full size (FSJ) 5.9 liter Jeep Grand Wagoneers, but beware. Many will not accept the double pully from the old alternator and are useless. The Powermanster alternator was delivered next day by desertcart. Well packaged, has instructions, no core charge or return required, priced reasonably, and it's obviously more professionally produced. Others I tried were either defective or would not take the double pully. If you have Grand Wagoneer with AC, THIS ONE WORKS!!! ## Features - Package Dimensions: 18.288 H x 23.876 L x 19.812 W (centimeters) - Fit type: Vehicle Specific - Country of Origin : United States - Package Weight: 5.964 kilograms ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001G9G774 | | Best Sellers Rank | #570,719 in Automotive ( See Top 100 in Automotive ) #2,007 in Automotive Replacement Alternators | | Brand Name | Powermaster | | Color | Natural | | Customer Reviews | 4.5 4.5 out of 5 stars (226) | | Date First Available | March 15, 2010 | | Included Components | Powermaster - Alt GM 12SI Natural 100A 1V Pulley 1 | | Item Dimensions LxWxH | 8.13 x 7.13 x 7.25 inches | | Item Package Dimensions L x W x H | 9.29 x 7.72 x 7.24 inches | | Item Weight | 11 Pounds | | Manufacturer | Powermaster | | Material | Plastic | | Model Name | 7294 | | Number of Items | 1 | | Package Weight | 5.96 Kilograms | | Part Number | 7294 | | Suggested Users | unisex-adult | | Warranty Description | Manufacturer Warranty | ## Images ![Alt GM 12SI Natural 100A 1V Pulley 1 or 3 Wire - Image 1](https://m.media-amazon.com/images/I/91Bbwe-PQXL.jpg) ## Questions & Answers **Q: How many amps is this alt?** A: 100 Amp.

Did swap out myself and I’m no mechanic!!! **Q: Does this fit a serpentine belt?
