I just saw this after a long winter of not checking the site, and no, there was not any factory spoilers available for our birds, there were however aftermarket kits available. I got one off of a 1986 a few years back, it looks more like a lip spoiler, not a pedestal wing type. I can take some pics this weekend to show you, I think the 86 trunk back end is the same as an 88.
