does not provide a needed shim.

The new tone ring is not splined and without a shim between it and the yoke, it will spin. This creates a wandering speedometer, especially under acceleration and highway cruise. The shim you need is .075thickness 1.54 ID 2.25 OD. Always use a new pinion nut (same nut as your dana 30/35/44 diff)and red loctite. Its a great kit, but get this shim and install it the first time.
