E34 extras

Do E34 come with dual airbags if so what year and did they come out with electric rear window visor.
Do all the rear seats fit on all year Models without modification because I have a 1995 model and bought an interior in almost new condition and the brackets are completely different. Is this normal for e34s
Thankyou

There are minor differences between MY's but for the most part they are interchangeable.

The first two things you mentioned came as separate options, especially dual front airbags. Those didn't come out until 1993-94 I wanna say.

See this for retrofits:
