The 86-88 walnut woodgrain is the same throughout all Cutlass/442 of those years. The only exception was the 87 442 to dark sheffield gray or sheffield gray. I've seen it both ways in the parts books. I have sets of everything except the RH sheffield gray vent plate.
To note for an FYI, the 87 442 shifter plate ONLY came with OD lens installed because you could only get that plate for an 87 442 which only came with the MW9 OD transmission. The other versions came with 3 speed or OD transmission lenses. If you are able to obtain one for a 3 speed and you need an OD lens or vice-versa, you can persuade your old lens out of your old top plate and swap it to the new one if you need to. Just be careful. They're glued in and if you just manhandle it, you'll break something. Use one of those cheap, snap off blade flexible knives that you can get up under the flange to cut the glue bond and you're good to go.
For the 86-88 walnut, 22528627 superseded to 22528650 was the part number for the radio bezels. Not sure the reasoning behind the part number change but it was in the middle of the 86 production run, as were a number of other minor changes for Cutlass in the 86 model year.
The 86-88 walnut woodgrain console and dash bezels for whatever reason could turn horribly pinkish when overexposed to the sun. It wasn't a week or a month, but over the years, you see original cars that sat in the sun and weather. And I've also seen examples where they just got darker, and not pinkish. The 78-85 butterfly walnut pieces seemed to be of a glossy smooth finish and as long as it wasn't rubbed on, tended to hold up longer than the walnut of 86-up.
Don't discount looking at early Delta 88s with D55 console, either. They used the same setup as the Cutlass. So if you see a
Delta 88 NOS top plate and you have a Cutlass with butterfly walnut and need one, get it. It's the same part number.
