Al,
In the mid to late 70's, Aspens, and Cordoba's, and such had mirrors that resembled E-Body mirrors. The heads looked the same, but the bases were slightly different. They had 3 screws that got bolted on from the inside of the door. Do your mirrors have 2 screws holding them on from outside? If so, they are probably E-Body mirrors. If you don't see any screws, then they aren't original.
