I climbed a ladder and took a look at the seats in the barn. The passenger seat seems salvageable. As for the driver seat, well, there was another seat bottom on top of that seat, upside down, which formed a little "cave" between the two seats. A critter, now absent, took advantage of that little cave and built a nest there, and tore up both seat bottoms. I don't know how much of the seat is required for a Mr. Mikes re-do, but it's probably toast.
So I recon you can have the parts car seats for $50 bucks. When can you come get them?
