I've been looking at getting a set of 3.73's, question is this- I know that I need gears, an installation kit, and fluids. The car only has 60k on it, do I really need to buy the rebuild kit?

 

Rebuild kit???I guess you are talking about the clutches for the limited slip.No you don't really need one but since the rear end is going to be apart you might as well go ahead and change the clutch plates.
Since you read these forums you know that as soon as the rear end is all put back together and broken in you are going to go out and see how the new rear end helped with your acceleration.How will you feel if you look back and see a big smoke trail behind just one tire?[:@]
