Here are some pictures of the rear portion of my car that is still original paint. Not great paint, but original.
Drivers side
Passenger side
The light pockets are flat black with the silver surrounding the rest.
the 3 filler pieces all are painted the same as the main panel. the textured silver.
Close ups around the tail lights. I suspect that during original painting they placed a formed cup into the light openings. As you can see the silver areas actually overlap the outermost seam line around the lights and is not real consistent around the perimeter.
Some of the pictures show the flat black still remaining and some are showing the reddish primer color. but you can clearly see where the silver ends.
Emblem placements
Jack instructions. Assumption is that it was placed on the lid with it off of the car because it is upside down when installed.
Fender/quarter cut lines
As for the above mentioned note that the 4 light recesses were textured. Mine are not. They are painted only a flat black. After reading this I even went out and looked closely to be sure and I cannot see any evidence of texturing. I am not the original owner so I cannot 100% be certain but...
I have owned it since 1983.
Mike.
