Wheel nuts and centres for restyle wheels

Does anyone have a set of wheel nuts for rostyle wheels. I am also after the wheel centres. They are 15" P5B restyles on a P6. I think the nuts are the same on both, but the P5B wheel centres are different.
I would be interested in non complete sets if anyone has any spare.
Failing that does anyone know of a supplier.
JR Wadhams sell new wheel nuts in a variety of stainless steel, chrome, brushed finished etc
About a couple of pounds each but are listed on their website.
