I am trying to convert my four spoke steering wheel to the 3 spoke sport steering wheel. I found the steering wheel, however, can't seem to find the round airbag that fits the wheel. Any suggestions, or is there a marketplace where people sell BMW stuff? I am new to this site and still trying to navigate my way around.... I tried auto salvage yards, only to have them send me a side door airbag...... tried e-bay... but can never seem to win... any suggestions are welcomed, or if you someone knows of an individual who maybe selling off parts, please let me know...
