I bought a set of fiberglass half door uppers with sliding glass windows today for my TJ. Not sure who makes them but the have big knob screws to attach them to the door. What I need are new screws and threaded door inserts. Anyone know where I can get these? I seen where Bull dog makes a set but the screws are different. No knobs. Also, one of the sliders had gotten broke and replaced with plexiglass at some point. Is there anywhere to buy replacement glass for it? Thanks in advance!
