69 Barracuda Seat Backs

Hi Folks. Does anyone know if they make Re-pop bucket seat backs for 69 Barracuda's? I am looking for a couple of new ones or bare ones that I can recover. Specifically in B5 blue.

I am actually not certain on what they look like or what they are made of. Cardboard, wood? Have seen some very vague pics that show them maybe with color keyed carpet or vinyl on them. ?

Thanks for your help.
