That's a 1969 deluxe, comfortweave bench seat interior. The seats are, anyway. Your door panels are standard, so I'm not sure what to make of that.
I've never seen this variant in real life, so it'll no doubt be made to your order, no one would stock it. I recommend you get new buttons, old ones are almost impossible to reinstall. Look at the backs of them, see if you agree. Glazier/Nolan has no problem with special orders, but I don't think they even list that one. As I said, it's so unusual it's probably not even on their charts.
--- That is definitely a 'unicorn' of a mustang interior - very rare. But we do have the pattern and Glazier Nolan is a great Authorized Dealer to purchase through. It's not in stock , but we're only 5-7 days out in production!
