1987-1990 firebird trans am headlight assys (w harrison)

I have a pair of headlight assemblys.
It is out of a 1987 trans am.
The books claim that these are direct replacements for 1987-1990, but they will also fit from 1982-1992, but I don't know what the differences are.
I also don't know if any of the electric motors are good.
I will take $40 for the pair or $25 each.
Or just make a offer, I hate to scrap them.
call show contact info , Dave , thanks.
[side note][the silver pair is all that is left, and the driver side one does not have a electric motor on it]
