Hello, Josh,
Thanks for reminding me about the material that you sent to me.
Thank you very much, again.
Yes, we used that material to match-up with original material found in a west coast warehouse.
It was used to cover a set of rare one-year small-truck optional Unison "Ride-Control" front seats.
Maybe Greg Hill will reply here.
Greg is a very knowledgeable a 1954 guy, who helps me with 1954-matters - and he helped me with the Unison "deal".
Maybe the brown door panels were used with the Pearl Beige interior cabs?
What is the color of the metal strip/edge around the cardboard?
Good luck with your truck/restoration.
