Steering wheel Boss

Hi fellas...
Any UK guys out there know where I can source a centre boss for a Motolita 14" wheel..... the PCD is 78" any help appreciated.
Kind regards

Thanks Bob 78mm is actually what Motolita state themselves for their wheel... so simply Tring to find a nice inset that fits.... Not a huge fan of the Pepsi insert so might have to save my pennies for the Gelscoe black version ... am sure it's beautiful but £150 plus the Gin and Tonic and postage is a bit spicy...!!!! The Gelscoe one is small and fits the Motolita 78 PCD
Lovely chatting with you yesterday Frank.... your smal Pepsil boss looks nice... I might be tempted. ....... loops ideal for anine lpoking to use a more original motolita.... . If I ask you to produce one for me how much would you be asking for...?
Kind regards Marcus
