Local cars all used only rubber/plastic bezels, in fact I machine these now from black HDPE (both types- >1968, and 1968>).
Nick, I know yours is imported...
The gasket you are after for the Bling UK bezel is aftermarket, made originally in UK. I think you will probably need to import them.
BTW these BlingThings also fit Oz cars >68, but not the later ones. People hack the angle to fit, but they are too small in diameter to seal properly.
