My 87 limited T has an annoying squeaking coming from somewhere in the rear passenger side interior. I have installed the rear seat braces, but the squeaking remains just as annoying. I have the back seat out. I just redid the headliner and nothing was a problem between it and the roof. Does anyone know of a typical problem wire or plastic piece that may be rubbing in this area-- before I start pulling apart all the rear passenger side interior trim pieces? Thanks for the help!
