Damaged shoot button - how to replace?

Dear all,

While trying to fix the sound and camera focus issue, i damaged the shooting button.

The Part 1 in the image, is connected to the button itself and i wasn't carefull enough and the cable broke.

From what i investigated while dismounting the camera, it's only possible to replace the whole Part 2 (metal frame), in the image.

Anyone knows where to find this? or fix the cable? (if it's even possible)

Best Regards,

José Cid
