Differential shims

I ordered two of the shims that go behind the planet gears in the diff from TRF. I pulled them out last night and noticed one is brass. The other appears to be a fiberous matrial. They have the same part number (134075 superceded to ATA7039). Has anybody ever seen these fiber looking deals?? Just looking at it doesn't give me a warm and fuzzy.
 
I have been told the later diffs came with fiber. Mine came with brass, if I remember right, about .045. Anything else? People always point to the broken diff bracket on the right side as being the cause of clunks, they don't mention the slop in the spider gears and the axle splines.
 
It's not that slop in the diff. is not mentioned, it's just that the crack in the R/F diff mount, in particular, is such a common source of the clunk and it is so easy to check that it deserves to be investigated first.
