Beautiful good evening, I have a question regarding my Audi 100 C4. Since it has a driver airbag, yet not with a passenger airbag, I wanted to ask if it would be possible without or also with amature board to retrofit a passenger airbag (which was available as standard in the c4) and if so, where I can get it with the control unit. Or do I just need the airbag and connect it to the control unit of the driver airbag? The costs of the conversion are not so important, de nn how to read vlt in my profile, there will be some modifications. I want to build myself this beautiful car really nice. Audi 4 Ever. Thanks already, MFG, Audifreak1919
