OK,
Going to have the new/new ones picked up?
Not to worry on the bracket, I will now cut/weld it to fit tight to the new rear firewall. This will give you the room for low profile 17's if you ever choose to go that route!
Doing final 'glassing & body work on the rear firewall. Overall you have picked up at least four if not five inches front to back! You're not going to grow taller are you?
