Can anyone ID these seats pls

[Guy67UK]

These seats were fitted in my 67 Step. I found them comfortable and wanted to get them retrimed, I wanted to see if there was anybody redoing the covers for them as I am going for a color change on the truck and want them either dark gray or black. But I have no idea what model or year of vehicle they are out of. It would be a great help if they could be identified and if anyone could suggest where I could get covers from, as I would have to ship them back to the UK.
