The good news, GP will likely replace the canopy if you call their customer service line.
The bad news is that they are on back order and won't be available untill mid November. Mine had a 3 degree mismatch between the canopy and the fuse. There was no way " a little sanding" was going to correct this. What I don't understand is that if the canopy and fuse are truly fitted as a set, there can be such an awful mismatch.
Good luck
