85 Cutlass Brougham said:
It will fit an 87 just fine, but the headlight wiring will be a little different ( the plugs to the bulbs), and it will have sealed beams and not the "Euro" lights that an 87 would have come with. The bumper cover is different too, as are the grilles and trim pieces. Also, search Ebay if you are set on the original type, but they are not cheap. They are quite desirable and fetch a good price. That's probably why they took it. In that vein, Craigslist may not be a bad place to look too, as they may try to sell it on there and you could tell the police if you see it.
I gatherred all he needs is the header panel. It would be more accurate to say "no, it doesn't fit" If you wished to replace the entire front clip with that from an 85, the header panel, bumper cover, headlight, all mounting hardware and wiring, but the header panel itself can not be replaced by the older style, the grilles are much larger and rectangular, the bumper cover also differs. The bumper, the fenders and hood are the same. If you need an entire front clip, you can normally find an 87/88 Euro clip complete for around $300. plus freight
