I believe these are original to the 84 - 89 G-body cars, they were installed in a new-to-me '76 targa by the PO, and are incorrect for that year, so I am passing them on. (I welcome corrections regarding correct year, fitment, etc.)
They are in very good driver condition, with all straps and snaps intact (don't be fooled by the pic showing what appears to be a missing strap in the right rear mat, you can see it in the other photo, the strap just wanted to stay tucked under the mat and not on top of it).
Some wear on the front and back of the driver mat, as seen in the images.
$80 for the set, including shipping to the lower 48.
Venmo only for payment + I am happy to send additional images if needed.
