I was digging around in the trunk of my '57 and noticed that there is some room between the floor of the trunk and the fenders. I started rooting around in the well on the driver's side and found a mirror. Almost. It has Casco stamped on the inside. I'm pretty sure it's this one... http://www.classictbird.com/Mirror-Kit-Outside-56_57-Order-2-Per-car/productinfo/17696B/ But it's not the entire mirror, what I found is the base that mounts to the car. I see where the actual mirror threads onto the upper portion. I wiped the dust off and it looks near perfect. I have no need for it, if someone can use it, let me know.
