[ROVERNET - UK] P6B NARDI steering wheel hub adaptor

[phing]

Hi I've acquired a sexy go fast NARDI wood rim wheel for RVW . Does any one have a source for a suitable adaptor hub for the NARDI 
wheel . There are 6 bolts , equally spaced, on75mm pc diameter
Moto lita advertises hubs and conversion rings on their web page but says they can't supply them !! This must be the hang out of the 
last of British Leyland's world beating  client oriented organisation  ??
Cheers
