If all fails and you end up having to have window reinstalled by private business ; make sure you do what I did. I advised my convertible top guy to reinforce window by adding a double stitch around window on inside. I also had my convertible top professionally cut from scratch; it came out beautiful. Adding the reinforced stitching also gives me an extra large bit of trust that my back window will not come loose. New canvas top, reinforced stitching . Total cost in California . $875. I would never trust Chrysler dealerships to touch my car.LOL. Seriously.
