when I got the above cab I also collected the "bench seat back" that came with it! (he was gonna throw it!)
it is a single piece back that fits into holes in seat brackets in vehicle already and then is secured with small slide bolts on cab rear wall...
ive never seen or heard of one before... has anyone else?
it appears well made...a long time ago! (is that dunlopillo?)
a couple of photos....
