Perhaps "hinge" is a poor choice of words

. It merely sits near the top. and the rearward end has 2 small tabs (not visible in the photo) that are under the lip while the rest sits on top of the lip inside the armrest. yes, it lifts, this is the part that holds stuff up top. If it weren't there you would just have a box to dump stuff in. How about this, send/PM me your address and I'll mail it out to you. If it works..Great...If it doesn't..throw it in the trash. No charge.
