Short of going to a Pick-n-Pull for a replacement, you should be able to just form a metal patch repair that easily. I would use both adhesive rtv and pop rivets. Your not dealing with much weight.

Unless someone has "modified" the bracket or stripped the threads, the rubber shock absorbers should just unscrew from the mount bracket. When ordering replacement absorbers, get the heat shields as well. I believe they increase the life of them above the heat of the turbo.

One quick note: Do a valve adjustment to cut down on the vibration that caused this in the first place. If it has been awhile, or the date of the last one is unknown, it is even beneficial to do it twice, about 200-300mi. apart. You will be surprised at the difference.
