Still can't find a proper part number for those hinges. Dang! Did over 1hr research last night while eat some corn, in the image I attached, next to the spring, that is the hinge in question, and they say to replace whole unit. The said spring has an arrow #1. Right next to it the busted part. From What I have heard both are busted. The pictures sent via e-mail and provided here are quite clear. Also, the other attachment is for whole assembly adjustment. Hope this help's. At this point it ain't a screw or rivet, it is clear in the pictures that Joe gave us, those hinges snapped!. Now what caused that is another question, maybe lack of lubricant, or other part snagging. Hard to know without having it in front of me. They don't look plastic to me. But I could be wrong. And if they are composite plastic, what kind of engineer would do that for such a folding hard top? hydraulics are involved here should be aluminum. I also noted 8.8 graded bolts, hard to believe this part is plastic. Like I said, I have never fixed one of these, only a moonroof. What I mean here, is if they bolted down with 8.8 grade bolts, that part can easily be replaced. Now where to find some hinges is a whole different story. After that, it is just a question aligning the folding hardware without scratching the paint. Delicate process but can be done. If it was me, I would have a apprentice/ buddy help and replace one hinge at a time while said buddy holds the other side. Quicker and not need to force your back. Cuz replacing the whole unit is a major PITA.
