Ricardo,
Please know that my car is a '92 (6/92, US version) and has the same wheel as later model US cars that I've been in.
Now, if you were able to use the airbag that came with your car with the new 400mm wheel, then the wheel you're selling is a 400mm wheel, eh? If you swapped airbags, are you selling the correct one that fits the wheel that's for sale?
Still not getting it, compadre...wish I could help
