1966 Dart window trim

SSVDP, great part breakdown pic. The part number surprises me as you can see the original part is a different number molded into the back of the part as I posted in my 1st post. Do you have an official name for the part? I saw one 2 years ago on ebay that was an new old stock and I didnt buy it because I figured I could find one but its proving to be a tough task. I had one member here give me one that is like new but that was a left side and so far I havent been able to find a right side yet. Thanks for the part breakdown pic.
