Anyone changed their rear end for more towing capacity?

Buy a swap 373 with disc brakes, rebuild it and swap it in. Should take you maybe 8 hrs from start to finish if it's your first time. you'll need a torch, some breaker bars and a buddy. probably get it done a lot cheaper if you bring just the rear to the drivetrain shop. you do most of the work you could probably do it for around $600. Ever have to take it to the dealer you could always swap the stocker back in. 3-4hrs.
