Holley’s LS accessory drive brackets make LS swaps much easier and now Holley has made it even simpler by offering complete kits with brackets, plus pulleys, and accessories. They use only the highest quality components from suppliers like Gates, Dayco, Bando, Sanden, Four Seasons and General Motors. Complete kits are available with A/C compressor, alternator and P/S pumps as well as kits that only have A/C side or alternator side brackets and components. In addition to complete kits components are also offered individually.
Looks like a factory unit.
