Just saved that link to my favorites for when I upgrade my gears. It might be cheaper to get 4cyl axles or bigger and better axles, but my buddy can do re-gear jobs. All I pretty much have to give him is some food, beer and I usually give him some cash for his time. Also pending how great your axle condition is you might be want to pick up a different set so you can sandblast and paint them. Up to you, you might be able to find a set for pretty cheap, do some shopping and see what comes up.
You do know you should never attempt to regear an axle unless your a experienced mechanic with training in regearing axles? If you aren't that take it to a shop to make sure it's done right or if it's an option do it with a friend who has done this job manny times before successfully..

i have someone to do it..i just have to get the parts. I've looked into swapping from a 4cyl but my rears don't have high mileage..have new seals and are in great shape...around here guys are selling 4.10 sets for $800...i'd rather regear my rears and not have to do alignment or other repairs to used rears i know nothing about. That Rusty's site looks like a good deal..i think the only other thing i would need is a carrier for the 30?
