The catalog record for this one is thin - it only shows up once, tied to a single year. If you're rebuilding a gearbox and matching gears by tooth count, this is a place to double check what's actually in your box before ordering, since gearbox internals varied across the years and we don't have enough here to confirm broader fitment.
Call the shop if you want to talk through what you're working with - happy to help sort out which gear you actually need once we know more about your box.
