The dashes are all pretty much the same from 84-91. Except the 84-85 318i dash has that Oxygen sensor light in the middle so you should probably get a later 325 dash. I got one for $100 and swapped mine out last week. Wasn't too bad overall but much easier to pull and install the dash with an extra set of hands. Oh yeah, if you can, try and get a later dash from an airbag car, they have an extra mounting bracket that is rivoted on. I got an early dash, so I had to cut the rivots and transfer the bracket.
