I've neve built one of these either, but I've done stockers.

1) I have no idea how to shim a diff, or what parts to buy to do this shimming. Some instructions on this would be nice.
2) "Assemble the differential according to the manufacturer’s instructions." Ummm....in this case, RCM is the manufacture isn't it? If a customer has a problem, they should and would call RCM first. So the instructions should be included with the diffs.
3) You reference some parts in your instructions by their street name. But in the diagrams and pictures they have part numbers, but no names. You should be consistent with this. Example - "flange bearings" must be the C8020's in the diagram?

Just some thoughts so far....
