The first 25 special edition Chrysler 300 kits will begin production in Jan '24  and are based on the exact aluminum/tailgate parts as the hugely popular Smyth 11-20 Charger kit. The 300 kit shares all parts with the Charger except newly shaped 300 bed sides.
 
To build the kit you must use the 11-20 fuel door assembly and the 11-20 Charger fuel filler neck.  The neck replacement adds an hour to the build compared to the Charger.
