OK I took some pics of the Manual on how the Shim Tool is used.

The first pic shows a top view of the Tool being inserted at the left end of the Differential Carrier and in the Shim/Spacer Area. You stick it in there with no Shims/Spacers.

You adjust the tool to take up the space and pull it out and measure the thickness of the Tool and it go find some Shims/Spacers that fit that size.
