Actually with the matching laydown light the window for the tag is aiming toward the bottom, not the top like oe. I got it from Drag also. I will have to find the part#. It was like around $25-$30.

Zooming in on your picts now I can see that there is no window on the top of your tail light lens. I found the part number at J&P which is 3400433 The price is $26.99, and, here is an image.
