More than 3.42 and you´ll start using more fuel plus an irritating higher revving motor.
I went from 2.80 to 3.42, just enough.

I went from 2.56 to 3.42 as well... definitely a good compromise.. I've got manual 5 speed though.

3.42 works well with a 3 speed, depending on what size tyres you have on the back.

Any higher and you really need OD, I run 4.11's in my 12 bolt. Which is great for launches, but it shreds tyres...

It´s best to buy new, if you buy a set out of the axle you´ll never get them set up correctly again.
You need to check the gear mesh pattern before removing them and installing in yours.

So if I were to find a place that would do this for me would they know if it would fit before I buy ?

Here's a bunch of ' em, choose the price you want to pay.

Do you have a limited slip diff ?

You´ll need an installation kit too, shims and bearings.
I used Yukon, supposed to be the best.

Don´t take my word for it though, you´ll have to make sure you know what type of rear axle you have.
