One of the challenges with a Gen III Hem swap is alternator clearance to the frame on the passenger side of the engine. The factory "car style" accessory drive system has the alternator mounted low & it gets into the frame in some applications (i.e. 1972-1993 Dodge D100/D150, and 1997-2004 Dodge Dakota Swaps). This alternator bracket mounts the small Holley alternator (197-302 or 197-303) low and inward for extra clearance. Fits Gen III Hemi engines with VVT & "car style" factory accessory drive systems. Steel construction with black powder coated finish. The Holley alternators are smaller & shorter than other alternators and easy to wire. The Holley alternator 197-302 & 197-303 does not require the factory Mopar ECU to excite the alternator, so it can be used with any engine control system (i.e. Terminator X, Dominator, and HP EFI systems).
