just took out my '53 GMC seat Sunday to pressure wash out rat & squirrel nests and...matter. Anyhow, the pipe tube looking frame and seat risers on the floor stay, you just grab the bottom seat cushion and pull straight out towards dash. For the backrest, you use a phillips to remove the 3 screws holding the c-shaped back frame peices to the large pipe-tube looking seat bracket, and pull it forward and out. Then you're left with an empty metal seat risers to the floor with the pipe-tube looking seat frame around it.
