you can try posting on ramcharger central. there is likely someone over there that will have the interior trim parts and is local or willing to ship them. trim is all the same from the doors forward. it is back that is different but them club cabs should be pretty easy to find trim for since they liked to rot out .
nice looking truck. might want to find a older dodge hood badge to go with the aftermarket grille. i plan on doing something similar with my truck whenever i can find a aftermarket grill that won't cost an arm and leg to ship.
