Most of the auto parts store people around here don't know what the hell they are talking about. I went into one to see if they could order my MOMO hub adaptor and they said that they can't because its illegal to put it in your car.
While this may be true then then told me that MOMO doesn't make a hub adaptor for my car!!!??? Anyways your best bet would be to google search it or just go with a company that you know makes a hub for your car. Hope this helps!
