OK, so I am recovering my old bench seat in my 72. My ? is... Should there be any thing on the lower portion of the back of the seat? there s the foam on the front with some jute padding on the top corners that go about 8 inches down. then there is nothing but the metal frame. am I missing something or was there nothing there to begin with? I believe it is the original seat but is has been recovered and seeing the way the previous owner did things ....well it makes me wonder.
