I need to replace the “U” shaped plastic trim piece that surrounds the back half of the center front seat arm rest on my 1970 Plymouth Cuda (pic). This piece is mounted between the two stanchions on each side of the arm rest. I want to search online for this item but have not been able to find the Chrysler part number in my 1970 parts book. The picture I provided was for a green interior, my interior color is black and this item would have been molded in black and not painted. If anyone has this part number or better yet this part, I would greatly appreciate the information.
