Well, I have an 89 that kinda sorta fits. It will mount and it will work, but it won't match and has no light in it. I used it until I finally found one from a 90 at the place that my parents bought my car years ago.

In the mean time, to make it driveable, the passenger will swap with the driver's side perfectly.
I recommend checking your pick and pull if this gets you no other hits as it's not really worth the trouble to replace it once and then again.

There is a cable for the light in the receiver that runs under the seat to the opposite side and over towards the front outside edge of the seat. To get at it, I found it easy to move the seat to one extreme and get at it from the opposite extreme, but I don't remember which. You'll have to cut the plastic zip ties that hold the wire up under the seat.
