Bought one on E-Bay from car-mast uk..cost about £14.00.
Covers the oval hole on the Volvo fine..connects to the female/male connector behind the spare wheel ok.
Ariel can be unscrewed easy if you need to put on a car cover.
Works fine.
Only thing you need to do is drill a 20mm hole as shown to access the nut to secure it...
Regards Colin.
