Ugh, sorry to see this! I would doubt that they have any individual soft top components available yet. And even if they did, it looks like the screws were ripped out of the structure of the soft top itself. It doesn't look like the bracket is damaged, per se. Hope you find a resolution that doesn't require a call to the insurance company!
I would also be going back to that parking garage to make sure the height limitations are clearly posted and that the measurements on the sign are accurate with the actual height of the garage deck.
