Here's one I was just talking to a guy about. He said he found it in a 66 Coronet, never restored, very rusty, that he bought in the late 1990s and is now working on. I've seen a lot of sheets, and this one looks to be in awfully good shape for an original. There's not even any fingerprints from the guys who handled it. I suspect it's a repro, but who would go to the trouble for a 66 Coronet?
I found two under my 69 500's rear seat. One was for what I got and the other a Bee.
