Need Help fixing my Z4

Okay, I managed to deploy the airbags on my z4 (Don't ask.....Very stupid mistake on my end.

I need your help locating airbags for my 2003 Z4, does anyone know if airbags from any other BMW might fit on the steering wheel and passanger side. I also need to locate the airbags for the knees.

The car is Souther Cali, and I was wondering if anyone has some bags for sale.

Thanks

keep your hands off the airbags and go to your dealer!
