Hello, I install tops in New Jersey for 38 years. I am very familar with all Porsches. I have been using GAHH for over 20 years. They are the first to make a boxster top with a glass window. They had issues with the field test, but have mastered their top. They are a great company and stand behind their product.
I was wondering how long it would take until Robbins would have issues with their glass conversion tops. I think it has only been a year or so since they introduced their glass conversion top. I am not happy with their customer service and their labor payment for a replacement of a defective top is a cheap miata top.
The plastic side pieces, can be used if a little broken as the tension of the top will hold them in. As for the side cables, perhaps the screw hodling cable (or lock washer missing) is too loose. Also, perhaps cable is too long. Try loosening the screw and pushing cable end inward while tightening the screw.
