Yeah, that's high. But there can't be many of these left in new condition and still in the Ford box.
Nobody reproduces these, and I doubt anyone ever will.
These trim panels were about $500 when they new, and are only correct for the 1985 and 1986 LARIAT models. I think I paid about $400 for mine (NOS) about 10 years ago when nobody cared for these trucks and before prices went through the roof. I even have a spare in great condition in my garage.
