I had noticed that my door plungers for the overhead light were not there and had a black putty plugging the hole. I asked the original owner and he stated that there never were any plungers there to begin with. Overhead light is manually turned on my rotating the headlight switch to its detent.
Also, the rearview mirror base is different as it does not have the recesses to receive the sun visor posts. It surprises me that they would manufacture a totally separate mirror base vs. just using the standard Malibu mirror base.
