A couple of photos:
When you cut the hardened composite be sure to do it outside and use a fan.
Here I am about to trim the window cover and am using an old furnace fan. I stay upwind of course.
I use an electric 4" angle grinder and cut off of a marking pen line.
I had the window cover unglued from the top for about a day and was getting some warping. A pretty typical occurrence. The part weighed right at 6 pounds. It should have been 3 but oh well.
I didn't want to finish the part as it would surely induce more warpage, so I marked the top for riveting it to the car, one rivet every 4.5". Improving the finish would come later. The car is going to be repainted.
Here it is attached to the car.
