WIW - Survivor standard black rear convertible seat cover

[69SSRSL89]

I’m in the process of restoring my 69 Camaro convertible and it turns out the rear seat back & bottom are in nice survivor condition. The previous owner covered them with an aftermarket cloth fabric. I’m putting deluxe interior in the car so I was planning to remove these and have to toss them, but them seem too nice to toss and someone with a survivor convertible with black standard interior could use them. Does anyone have an idea of what these might be worth and know anyone looking for something like this? I have attached a bunch of pictures and there is a small flaw, but for original seats they are in nice shape.
