They are custom-fit to each differential at the factory. You need to measure your shims when you take the diff apart.

+1. The pinion shim is usually the same when you change gear sets (assuming you use frapp gears, or the pinion depth stays the same). The carrier shims depend on how the gear backlash is set up during install. Even with the same gears, the carrier shims may need tweaking to provide proper fitment.
