Logic board mount/ bracket stripped

Replaced my processor and ssd. Works like a new beast. Unfortunately I managed to strip the screw holes on the mounting bracket for the logic board by the USB ports/under the fan. There seems to be quite a bit of resistance against the board and the ports arent close enough to the chassis to get a connection externally. Thoughts on how I could go about fixing this? I assume I won’t be able to find the bracket to replace it.
