Well you can order another diff at atomicmods if you screw it up. But take the stock diff apart. You will see a big blue gear and 3 little blue gears. Take the 3 blue gears out and the spacer that holds them in. Then you will see another big blue gear. Glue both big gears to the case of the diff. make sure your driveshafts fit in before it dries. After its done drying put the gear back together and put your car together again. You will have all power going to the rear wheels and you can drift with ease, but its easier to strip the glue out than you think. So be careful with the throttle and only drift on low grip surfaces like on linoleum (sp?) and stuff. If I take off at half throttle on carpet and hit full when it picks up, I can do nice fishtails and can actually get the car going sideways on carpet.
