I have tried to read the threads here, and reviewed Utube, and other places to try to figure this out. I have seen notes that there are either screws or pins at the end or ends, and some notes on clips along the roofline. The directions that come include noting that there are pins at the end and use glue in between. So, before I screw this up like everything else.....thought I would again raise this question. Has someone done this on a hardtop, and if so, can you tell me what you found that works, and what does not. IF there are indeed clips along the way, can you describe how they work......thanks for thoughts.
