Ok i have a 1996 mustang gt and i am going to be installing 4.10 gears in her. I am fairly mechanicly inclinded and i beleive i can do it myself i was just wondering what i will need to go at it. Firstly i know i need special gear lube for new gears and of course the gear set, But do i need an actual kit like this?http://www.brothersperformance.com/c...oducts_id/2326

Then is that all i need or is there even more things to buy. I know i should probably replace the axle bearings but the dif has been recently rebuilt so idk if that had been done at the same time.
Please any help is appreated thank you.
