Here's one from Eff One Fifty's previously recommended source:

I forgot the pinion seal in my above list. For whatever reason the pinion nut is not included in the minimum install kit. I would buy one from the seller separately. You
could reuse it with thread-locker but they are a one-time use self-locking design so I would get a new one with thread locker already on it.
Before you buy any install kit, figure out who is doing the install. Anyone who knows what they're doing will tell you what they need (and it better be either a minimum install kit + pinion nut or a master install kit).
And for whoever recommended to replace the pinion bearing, you didn't mention which one! You know there are two of them, right? The inner isn't any more or less important than the outer.
