Hello does anyone know the dimensions of the two pieces of Masonite inside the vinyl cover in back of the arm rest cushion. The assembly has the wire that attaches to the top and two pieces of Masonite it hides the mechanism. I know this is a long shot but maybe someone has one laying around. Thanks for any reply .

  The top piece is 63/4 " long, 6" wide at the top and 5" wide at the bottom The top piece is notched at the top for the spring clip
 The bottom piece is 73/4 " long .43/4 wide at the top and 31/2 " wide at the bottom
 Hope this helps
 Carl
