Check with a dealership to be sure whether you want part number 89452-28030 or 89452-14050, then look at the entries in the list linked to below for that part number only.

Any dealership or decent parts shop should be able to cross reference the part number (provided you have the right part number). FYI, it's not really worth buying a used one if that's what you have in mind; They are a wear component.
EDIT: from looking at the list I'm pretty sure you'll want 89452-28030.
