Help Identifying a Seat

[JoePolo]

Was headed down a local street near my house. And saw this seat with a sign that said “Free..1967-1972 Chevy Truck Front Seat” of course I tossed it in the bed of my truck without hesitating, because I know the owner of the house it was in front of owns a 72 GMC Jimmy.

After looking at it, the brackets are odd and the width of the seat almost seems like a rear seat to a Blazer but not really sure can’t find any brackets online that seem to match. Perhaps the rear to a square body K5?? It’s 40 something inches wide I forget the exact measurement.

Any ideas??
