You will also need the bearings and seals and crushwasher and all the other little pieces for installing the gears.

I wish we could just sticky "Rear-ends are precision gear assemblies and NOTHING inside them is drop in. You will need bearings, seals, lots of shims, crush washers and other stuff, as well as significant labor time at a shop that specializes in this work. You CAN do it yourself but you will probably screw it up and turn everything you just bought into expensive paperweights"

All of that stuff comes with the gear (or at least it did when I purchased from Z1). The only thing I needed was shims but you wont really know which ones you need (theres like 12 different ones) until the installer measures with a dialer for lashback. Let the shop deal with that headache lol

Thanks for the advice. Def not doing it myself and didn't want to buy a sport manual pumpkin if it isn't necessary. Sounds like you're saying that if I have the correct install kit (bearings, seals, washers, shims, etc.), the manual quaife lsd and 4.08 would fit the open diff on a base 7AT. Is that right?
