One lovely Pre-NEW old stock Mopar 2585104 RIGHT hand OUTER tail lens (passenger side) fitting 1966 Dodge Dart. The casting number on the face of the lens is 2575504. 

The lens is RUBY red....my camera darkens the photo.

Dart lenses went through several assembly steps to arrive at a completed product. This lens never made it to final assembly at the factory. It is the red and clear plastic lens only. You will need to transfer the die cast trim from your old lens to complete the lens.

Customers tell me the chrome mylar trim like Cowles® #37-078-01 is a great substitute should your old die cast trim be bad. The trim is quite cheap.

I see finished lenses selling in the hundreds of dollar range. My lens is for one who has more time than $$$$$$ and is up to the task.

"When only NOS Mopar will do".
