You'll also see this part listed under the older W578 designation, which is the same physical piece under its legacy letter-prefix number. If you're working from an old parts book with that reference, this is the modern equivalent.
We don't have a lot of extra detail on file beyond the year span and part number, so if you're not sure this is the right spindle for your fork setup, give us a call and we'll confirm before you order.
