Product code: 1946 1947 1948 DeSoto or MOPAR Tail Light Bezel w/ Red Glass 2024 Lens, Heavy Original Piece
As I understand it, this would fit both the MOPAR and DeSotos of 1946, 1947, and 1948. There is a part number on the inside of the chrome bezel that appears to be CB13756. This bezel is in used shape, showing bubbles in the chrome, no major rust issues, and the glass lens looks to be in great shape and is probably original to the assembly. I am assuming this is for the passenger side, but 2024 don't quote me on that.
Shipping quoted is via Medium Flat Rate Priority Box, as this is a fairly heavy piece of chrome and glass. It will be fully insured for your purchased price.
