Found mine under the the 2nd seat rear cushion. i had to unbolt the folding cushion from the wagon and remove the rear cargo floor from the seat cushion the build sheet was between the cushion and springs looks like it was just put there perfect condition. I found a second one under the carpet on drivers side 2nd seat footwell it was intact but. looked like it was soaked in oil is a little hard to read, Hope this gives you a couple ideas where to look.
