Overview
This kit is part of a three-step process to correctly install accessory drive brackets. It requires users to first determine their belt alignment based on crank pulley position, then select the appropriate Holley accessory drive brackets, and finally use an installation kit like the 21-2BK to ensure proper alignment. An application-specific installation kit is mandatory for most setups.
