Help Identifying Seats

[AK 99]

Does anyone recognize these seats? Seller says he doesn't know where they were pulled from. Might not even be gmt400 not sure. Thanks

Those are aftermarket seats from back in the day. I'm pretty sure I installed the exact same model of seat in a customer's truck. The seat fabric mimics the original material used in the early 90's. Iirc, the seats adjust individually, including the center jump seat.
