Hope it works for you John. The real 190 canopy actually was split at the top centerline part way along the length of the glazing. It could be an option to do the same on your model, drilling a small hole at the end of the split and then sawing the plastic with a very fine saw (I have PE ones for this type of thing) up to the hole. Once the desired angle is achieved, the sawn split can be filled with CA. Not sure I'd have the courage to try this myself but thought I'd throw it out there.
