Ditto comments above...I believe you need #24s (and perhaps the circlips too, #25s). If you go to the database...copy and paste the 11 digit BMW part nbr for #24...then call you local BMW dealership's parts department and ask for a price quote for that part nbr. You can also go online to get an idea of what vendors are selling them for. It may be cheaper to order them from your local dealer and pay local taxes vs buying online and paying shipping...unless you can find a vendor that will through in free shipping...which may require a minimum purchase amount.
Good luck...your local BMW dealership's parts department can also verify if you have the correct part nbr, too.
