  • 98-02 Camaro, 99-13 truck 105amp, 145/160amp alternators will not fit without grinding on the block and or alternator. We recommend alternator part numbers 92254798, 92254672, or equivalent for bolt on fitment.
  • If needing to extend your alternator harness connection, use ICT# WEALT30-36 (4-pin) or WEALT40-36 (2-pin)

*May require slight grinding on block (see photos) if using a 105, 145/160 amp alternator.

**If using an Iron block engine, we recommend our SKU 551921-LS01 to add the third mounting hole next to the timing cover. This threaded hole is only factory in aluminum engine blocks.

***This can only be used on blocks with at least 2 mounting holes on the front of the block. Blocks that only have 1 mounting hole will require drill template 551445 to drill and tap the 2nd M10-1.5mm hole. This hole is in a non-critical part of the block that is away from the cylinder, oil, and water jackets. This bracket only bolts to the front face of the engine block.
