I've got a great 66 GMC Carryall in really nice conditon
and can't find out much about the seats. The front
seats were apolstered some time in the past and in
great condition. The back seat looks like it should really be the 3rd seat cause it's wider than the middle should be. It does have a small, curved notch at the bottom of the back on each side? Should the back be straight & without the curved cut-out? Where is best place to find a middle seat?
