Whats the correct mirror??

The correct mirror is called a dual post mirror.They came on 63-66 A-bodys.I dont have a pic,but it is pretty explanatory it has 2 post's.

From the looks of your pics,the dual post will not match the holes of your mystery mirror.Nothing that cant be fixed.

Hope this helps.


Might be interested in the remote mirror.
How much are you asking?
What kind of shape is the chrome?
