I just bought a Nardi wheel on Ebay supposedly off an '80 SLC. I did a little (too little) research and decided it would fit my wife's '76 SL. The wheel is beautiful but the hub adapter hole is way too big for the splined shaft of the steering column. Does anybody know a Nardi wheel expert who could help me (1) determine what my adapter will fit so I can sell it, (2) get the right adapter for the '76?
Thanks.
