Can someone help id these mirrors please

[mkayers]

I bought these rallye mirrors from a member on here about 6 months ago. He said they were from a Dart Sport but should fit my 1970 Duster. When I got them the bottom was totally different, like there should be a base that mounts to the door. Is there a base I can get to make these work or does anyone know what these are so I could just resell them to get the correct ones?

Those look to be GM mirrors, maybe a Camaro or Bird? Definetly not Mopar ones but I have heard of people using those cause they will work, just not correct.

Nice, maybe I'll tear them apart a bit to see if I can find a part number.
