I believe the trunk liner was some sort of art board about 1/8" thick. Try and art supply store for the material. Also, the black was only on the passenger side of the panel. The trunk side was natural cardboard.
I think you are right. I did some searching today at the local shops but no luck. Not even close! :banghead:
However after going through Johans trunk divider I found evidence of how it was placed on the car. When you popped the trunk you should see the black area behind the seat. The reason for knowing that is that on the pictures you can see the marks after the crossed bar behind the seat.
On the not painted area is marks after the seat spring going vertically.
Kevin! The way the trunk divider was placed might have been different between the assembly plants?
