I believe this seller has been discussed at great lengths at this link and starts about halfway down the page.

Pic isn't great but stamping doesn't look right to me.

Ring gear shown is the standard 4.10 - not the COPO.

I have one example of a real axle , 0306 date. Dought this real, crappy picture of the stamp.
