I've seen alot of mustang magazines that sell tops in them. How ever they only sell the top. Also I've never seen that back piece sold by itself it's always sold with the glass or plastic. I already have the glass with the defroster what I need is the top part and the back part where the window is. I've seen the top sell for $190.00ish and the back part for around 160.00. I would not be installing this myself but my uncle has done his z-28 5 timses. Any help would be awesome. Thanks
