Hi, I've been doing some reasearch on different install kits for rear ends, and I found that most of them contain different parts then others. I was wondering what parts do you need for just changing out the gears. So far I have:
Pinion shims
Solid pinion spacer (replaces crushed sleeve)
carrier shims
pinion seal
pinion nut
cover gasket
outer pinion bearing
head bearing
If I dont need some of these or I'm missing some, please let me know, thanks.

What kind of rear end are we talking about?

If the bearings in the kit do not include races GET THEM TOO!

As long as you have your axle apart include new axleshaft bearings and seals.

Make sure if you do the work yourself to beg, borrow, or buy both an inch pound AND foot pound torque wrenches, a dial indicator, gear marking compound, you can forgo a pinion depth gauge if you have opted for the slip fit pinion bearing, this will allow you to check tooth contact pattern, and adjust as necessary without pressing the pinion bearing on AND off several times.
As you have opted to go with the pinion spacer instead of the crush sleeve, you will find you may need to install the pinion nut and remove it several times to set the proper torque setting for the bearings to last as they should.
