1957 Chevrolet convertible interior rear stainless moldings pair - $75 (Ankeny)

I have for sale a pair of New stainless interior moldings for the rear of a 1957 Chevrolet convertible.
I believe these are the pieces that go on the interior side panels next to the back seat.
These are new pieces that have been on the shelf for a number of years.
I do not know for sure if they are reproduction pieces or NOS GM.
$75 Thanks
