Did the 1976 duster come stock with interior lights

hahaha, you gotta be kidding. However I do remember in the mid 60''s used car advertisments in the paper, regularly touted "R&H", meaning radio and heater equipped. Yes, that was a real thing back then. But by the late 60's, early 70''s it was a rarity to not have those "options ".
I remember commuting to the U of W with a HS buddy of mine in his '62 Falcon which had neither a heater nor a defroster, but I believe it did have dimmable dash lighting, hahaha.
