Hello! All help is appreciated here. I found at our dealership buried in the attic (before us this place used to be a Chrysler dealer) a new in box door panel. We have no idea what it is from. Tried to search the part # but got nothing. What do you guys think, we were thinking Dart? Again your input is appreciated!

 

this might not help. but it looks long so it might be for a 2 door. and the cavity at the front may indicate a newer car with a lever, not like the older cars with the door handle on a shaft. and the wood grain panel may indicate a sporty type car. and not a cheap model. just a guess.
