will this fit and for lsd do i have to buy both sides of axles and how much are nthey from raxles thnx guys

 

For LSD you will have to replace the axles...for regular you wouldn't. Raxles axles are $125-$150, but probably more since you won't be able to return a core (although they might not notice the difference). It was thought before that the 4th gen speed sensor had to be used, but I have the 5th gen one in there since the tranny came with it.
