We welded one up on Rubicon way back in the day. Buddy had his knuckle studs sheer off, and while replacing the knuckle studs someone noticed the crack in the Birf. We used an air cut off wheel and ground out a nice trench in the birf and welded it up. It was ugly and not smooth but it was a nice weld, we never ground it down, we slapped it back together and wheeled it from Big Sluice out the tahoe side with no issues. He was a cheap b*std like me and ran it for a couple more months before finally breaking it completely out at moonrocks. And he drives that truck like it's his ex-girlfriends, so I know it saw it's fair share of abuse.
