Since there's no back seat in my truck anymore, I needed to get rid of the seat-backs, or find a way to hide the holes they'd leave behind. I went about half each way. Once you unbolt the lower parts of the seats, the "upper seat back" parts can be simply pulled away at the top, and lifted out. The stock covers are just velcro'd on, and very easy to strip off. The inner structure is the two back parts here, I'm going to use some .063" thick ABS sheet to "skin" them to match the pebble grain in the rest of the interior. YAY! ABS is what they're made of, no bonding hassles here. A liberal application of ABS cement, making sure I got out to the edges. The edges are heated and bent over, and trimmed. And the corners carefully rolled. Finished one, and then made the dupe for the other side. What the reverse side looks like. Snapped into place, it looks like a matching part. Note: these parts are contoured to the cab wall, they weren't warped by this process. Took about an hour to make both sides. I need to find some suitable paint to match them in with.
