If you are installing in a V6 housing you can use the factory bearings. If it is a 4cyl housing you need bearings that have a 50mm V6 inner and 4cyl outer. ARB only makes one locker for the 8" Toyota.

Timken also makes one under the same number and if you have a local bearing house they can prolly part match to what ever they sell.
Let me know i can get you a good price on a set of em.
