Newbie wondering what year/style of bucket seats are these

Those are some nice looking seats. I would be careful "sanding " the backs of those. You dont want to lose the texture.
Thank you! I was a little worried about sanding them as my fingernail can scrape off the textured part! I wasnt sure if anyone had refinished them before. Was wondering what others had done as I was thinking about trying to repurpose them and if it doesn’t turn out well the spending the money and paying the shipping from legendary
Thanks!
