crown for tail light rings

[Imperial59crown@xxxxxxx]

I recently walked away with a crown trim piece for a '57 Imperial on eBay, 
and from the picture, it looked as though it maybe the crown which goes on 
the chrome part of the armrest in the back-seat. My car is missing one, but I 
am also missing one of the small 2 pronged crowns which attaches to the tail 
light rings. I've tried most of the big Imp. junkyards, but have been unable 
to locate this piece. Anyone have any leads or ideas, short of fabricating it 
myself?
