I must say you're a brave man. It would be very scary for anyone to cut a roof open like that. I always wanted a sunroof for this car and wondered how much it would really affect the structure of the car.
Did they use the same headliner fabric when they cut open the roof onto the shade? It's a perfect match from the pictures.
Whoever did installed this sunroof for you did an excellent job!! If i didn't know about this car, i wouldn't know it was done aftermarket. The dome light shifted to the back to allow the sunroof to be in place looks as if was meant to be there.
I wonder if it's the same dimension as a regular protege? If the install was done well, which it clearly is shown there, i don't think you will ever experience any leaks.
One down side to the sunroof is how they used such thick rubber to surround the primeter of the cut out just to prevent leaks to seal it tightly.
