The shims usually belong to the diff. It's possible that the diff didn't need any shims.

When you install the new axles, the C clip should have just barely enough room to install...........the axle should have almost no end play.

When I did the SD, one of them wasn't quite perfect and it probably has .010" play..........I'm not overly concerned about it.

Most of the time the shims stick to the diff when you pull out the axles. Check on your diff and I bet you find them there.
