Saw some pictures of what is reported as the dash bezel from a 400 to 700 series Dodge truck. Said to have been used throughout the 70's in the bigger trucks.

If this is the case, I will be scouting for these. I think its a nice looking piece.

I personally have never seen the inside of the heavy duty trucks, so I dont know.

My thought was if its not from the HD trucks, maybe another Mopar in dash application, and thats why the wiring looks to be plug and play.
