Don't know if the 87's were equipped with these, my 87 LS is not. It is a rear-view mirror from an 88 Cougar with the auto dim feature for headlights. It automatically darkens when the lightshiznit it. The mirror is in great condition, in fact it looks new. I haven't seen them before on the Cougars, but I don't know how common they are.
I'd like to have $15 + shipping. Lowered price...
Still got it...
