leaking steering box

OK so I know its time for a new steering box on my 96, because it is leaking pretty bad. I have never played with this item yet. So how difficult is it to replace? Who sells a new one for the best price? I also really need to get a brace probably the reason it went bad since I am running 33's and 6.5" of lift. Any insight?

Try ebay mine was leaking out so bad that a quart was gone by the time i was out of my driveway haha but i got one of ebay for 65 shipped and put in for 75 but from what i hear it not all that bad to do yourself. but go that route its always a good deal
