I have read a few posts about people wanting the 13 tail lights on thier 12 Boss. I know there is a gap if you try and install them on a 12 Boss. My question is, can you swap the rear bumper skin from a 13 to a 12. They look very similar but I dont have any Bosses I can park side by side to figure it out with. Does anyone know if the rear bumper skins will interchange or did they alter other parts of the sheet metal so they arent compatible?
