The catalog record we have on this one is brief, without the usual figure titles or model-year spread that let us describe exactly where it sits in the gearbox or which years it was cataloged for. If you're working from a parts book that lists 57-4416, this is very likely the same assembly, but we'd want to confirm the application before you order.
Call the shop with your gearbox casing or existing layshaft on hand and we'll make sure this is the right one before it ships.
