Sorry, you should place WTB in the parts and parts section, or write to trusted watchmakers who may have spare parts.
Also, you can try writing TD to search for details, for example Trusty. Now is not an easy time to shop, but maybe they can get the XF PAM127 CG for you.
Also you can look at marketplaces like eBay, but I usually don't find suitable ones there (inverted CG for 47mm luminors)
