I can't see the picture, what seat did you get and what was it out of?

Starting in '78, K5's got a "fold and tumble" type seat. The front legs of the seat are hinged and bolt to the floor. The rear of the seat latches to pockets in the floor. The seat back has a release lever on the passenger side, to fold it down. There's also a latching strut rod, that holds the seat in the folded and tumbled position.
