I bought a couple of these from motorsportauto in the US, since I couldn't get it in the UK for whatever reason - cost was $41.90 USD for 3 inc shipping.
My Z is now sold, so if anyone wants one, ill send them to you for the postage cost, they are unopened (So if they don't match don't blame me!).
its Genuine Nissan, paint code QAB
first come first served etc
