Bucket seat Identification

[ImNoSpaz]

I have a set of buckets that I think are from a Blazer. I'm in an argument about that. The rail holes are 11.5 inches front to back center to center. Side to side measures 16 inches center to center. Carpet backs and I don't know if they have been recovered or not. (wish there was a build sheet under there)
Any help appreciated before we start rolling in the dirt over this! hehehe

Not an expert but they look like utility buckets. They could have been on lower optioned Blazer/Jimmy, Suburban's or utility panels. The upholstery is not original, the backing would have been a hard panel.

Utility buckets had a metal back. They don't look like a Blazer seat.
Also, the Blazer passenger seat doesn't fold like that.
