I have a terrific deep dish rubber trunk liner/tray in my 2007 Charger from Mopar. I have been looking for a similar liner for my new Challenger to no avail. The only one available seems to be a Weathertech universal. Since I often transport swimming pool chlorine, that just doesn't cut it. I decided to try the liner out of the Charger and try it. Low and behold, it FITS!! Not quite perfect, but very close. The "wings" near the taillights don't quite go all the way to the edge, but otherwise it is a pretty good fit.
