I am posting this for Ron, "Old Gasser". He says he still can't get back on here. He is looking for a plastic waste basket, that was a dealer option in 57 & 58. I guess it hung over the kick panel on the passenger side. Myself, I never knew they offered one. If you have one to sell, or know of one let me know.

But that is all I found.
