63 tail lite

Ok .... Iv seen this lite before on 63 and 64 dart convertables only. As I am parting out A 63 ppl want the tail lites but the ones on mine don't look like the ones thay have. One guy said the screws were in the wrong place ... the next guy said the ring was wrong ... the next guy said his didn't have the vertical thingy and the next guy said he had never seen one like that before. ..... The lens I have isn't flat like all of them ... It has a chrome ring in the center like some ..... and a extra bit of bling like few. ... So is the vertical thingy a dealer instaled thing ???? Or is it a thing thay did at Newark just on a whim in late 63 early 64 ????? Im sure thay are out there on a GT hart top or on A 170 I just haven't seen it. little info would help here so i can better help the ppl im dealing with .... tnx
