I did the Durango box swap from a junkyard. It started leaking after about a year so I did some research and discovered Red Head Steering. Shipped it to them, in Washington state if I remember correctly. They rebuilt it and got it back to me within a few days at a reasonable price. Been good so far, about a year. They have some in stock too, so they can ship you one. There is a core charge if you go that route.
