why?
the side lamp housing were painted while installed on the car, thats why the rear sidemarker retainers (located in the trunk) have overspray on them, some more than others. so when a car got billboards and since the sidemarker housing was painted to match the cars body color, the assy line worker would remove the body colored housing and pick an already painted white or black housing out of a bin and install that housing to match the billboard color
These types of facts always blow me away. Who'd have thought some trivial action completed by an assembly worker, day after day for a year(s) would be so critical 40 years later.
