67 Dart/'Cuda rear armrest bases, in black

Anyone got any rear armrests in black plastic for a 67 dart or 'cuda? I need some but have only come across chrome ones, I'd prefer not to have to paint some to match my front armrests.
Prefer if you can post to New Zealand, but I have contacts in CA.
Prefer to pay by paypal but let me know what suits.
Thanks.
