Yes, I had to repair my front box from a crack in pretty much the same location. Mine occurred when I had a road gator thrown in my direction and I ran over it throwing it into the storage box. Made me feel good to have the box damaged and not the trailer itself. I had the repair done by an auto body shop that specialized in Corvettes, I tried several boat shops in the area but they wouldn't touch the repair.
Several people on the forum have done repairs by themselves, I won't try that.
Search the forum, my damage pictures are somewhere under "front storage box" is it necessary I think. (to lazy to look it up)
