Go to Melett turbo's website and search using your turbochargers PART number. Try the number in both of the search boxes on the home page. Bring up the exploded views / part numbers and it should also list a Melett part number for the rebuild kit that you need. You can't order directly through Melett unless your a dealer. Melett suggested that I contact XS Boost Turbochargers in Ohio for parts. They have great prices and quick shipping, and should be able to get anything listed on the Melett website.
