I'm not sure about differences from one kit to another, just make sure it's for the van and it has all the pieces. It should include strainer, strainer gasket, and pan gasket. The kits I have use cork for the pan gaskets and paper for the strainer gasket. I'm indifferent to the type of gasket material. I've used both and never had a problem with either. If a person pulls the pan and does a service every 60k miles (like you're supposed to) either type gasket will do the job. Tim

PS: You are correct, 2wd & 4wd use the same kit.
