I'm still in the bodywork phase so I haven't spent much time inside the car yet.
I've known the dome light needed a lens but never worried with it, I was just checking out new lenses and it hit me, there's a 1st gen dome light in my car!
All the dome lights I found in searching brought up the round lenses.
I know this is pretty insignificant, I just think it's interesting because this is one of the first '70's made, I guess they were using up 1st gen parts in the beginning.
I did a search and found nothing about '70's having this style dome light.
