The lower dash on my '91 was broken near the diagnostic connector. I did get it off and repaired it . There were 2 screws on the side, 2 on the top and 3 on the bottom. The side and top screwed into the same kind of extruded u nuts. The 3 on the bottom were a little longer longer with different threads and a sharp point. They screwed into something that felt like the same u nut but I couldn't really see it. For some reason, one was missing. Is it the same as the upper ones? And where can I get one?
