Camper Mirrors

[vespaholic]

My newly acquired 1979 C20 has the wrong mirrors.
It should have camper mirrors.
I found 2 for sale on different trucks, from different sources.

One is on a 1982 truck Driver Side
The second is on a 1977 truck Drivers Side.

Are these mirrors the same from 1977 - 1982?

Are they the same from left side to right side?
Do you just swing the head around and over to the other side to make a drivers side mirror into a passenger side mirror?

Thanks in advance!
