Replace the rail.
They don't make them, but if that's the driver's side there's one available on here. Lee Robinson is the seller, shipping will be expensive for you but I've done business with him before, he's a good guy.
Here's the listing, you'll want the rail for the standard bumper brackets (blue one). Even has the shock tower attached...
