Exact fit for 2002 Vortec 8100 (8.1L 496). Disappointed that the kit didn't include a metal spacer/washer for the front of the pulley, but the instructions say newer pulleys don't require this so it can be left out. I did not reuse the old gasket from the old pulley as it was rusty. No problems so far - about 5,000 miles.
