Does anyone know if the gear shift selector console in my 1985 300SD have a light, cuz sometimes at night its difficult to know exactly what gear I'm selecting.

I saw the post of the new 1983 300SD, I think its bit to high, he's not going to get that much. However, I noticed that the rear seat has headrests and they really look cool. Would it be difficult to have these installed in my 300SD.
