BMW Repair: auxillary pusher fan blade, bmw m3, fan blade

Question
hey i have seen parts for a 1999 bmw m3 auxillary fan for the whole assembly. but all i need is a fan blade for a auxillary pussher fan for a 1999 bmw m3. if i have to i will just buy the whole assembly but i was wondering if i could just buy the blade.

Answer
I have looked before and have never seen a listing for just the fan blade, so I would just purchase the assembly, also the blade is ballanced so if you bought just the blade you would not be able to ballance it and it would vibrate.   hope this helps.......Thanks Nathan Babbitt
