Allows Corvette or L99/LS3 Camaro alternators to be mounted on truck & various other alternator brackets. (these alternators have a wider bolt pattern than other LS vehicles). Also can be used to move the factory position of your current LS alternator location to gain clearance.
Will not work with CTS-V Alternators (these have a 3rd side mounting hole)
