Yahoo auctions japan have them, eg http://page8.auctions.yahoo.co.jp/jp/auction/h182937399" onclick="window.open(this.href);return false;
I recently purchased a set in shadow/black chrome to replace the gold(!) ones on my Cima. They were OEM and excellent quality repainting.
If you can't buy direct from Yahoo japan, contact Jesse Streeter, he sourced mine and I have used him for a heap of stuff over the years. http://jessestreeter.com/" onclick="window.open(this.href);return false;
