This may be an entirely useless bit of information, in which case I apologize, but one of my family gets things from Pelican Parts in America for his '89 911. He doesn't have any problem importing, even with very small items. Their website is pelicanparts.com

Alternatively, have you tried AFN? They keep almost everything, and would be worth a 'phone call. Martin Pocock is Parts Supervisor on 01483 408803, or [e-mail]
