Hope this post is in the correct forum. So, I have a 2011 GT500 with a glass roof. The glass roof shade has a crack in the track... (somewhat common in this year I believe). I leave it open, but would love to have the option to close it. How difficult a fix is this....is it a garage fix or better left to the dealer or some type of an interior specialist? I’m moderately handy, but I have my limits. Thoughts?
