I have the original one off my '67 right in front of me. I am about 90% sure it's original and not a repop.
The base has the letters HA 61071 and on the other side has CAV X-2.
The mirror does not have anything on the back side, but the glass has 4-DCA-4 (printed backwards) on it.
I am not going to use this mirror, so if anyone is interested in it, please let me know. It is loose around the swivel point, but otherwise is in great condition.
I used to be indecisive. Now I'm not sure. I feel like I am diagonally parked in a parallel universe. 1968 400 convertible (Scarlet) 1976 T/A - 455 LE (No Burt) 1976 T/A New baby, starting full restoration. 1968 350 - 4 speed 'vert - 400 clone (the Beast!) 1968 350 convertible - Wife's car now- 400 clone (Aleutian Blue) (Blue Angel) 2008 Durango - DD 2008 GXP - New one from NH is AWESOME! 2017 Durango Citadel - Modern is nice!
