The second one looks like alphabet practice.

This condition is typical of the quality and performance issues encountered when a replacement worker is assigned to an element and does not understand how to properly perform the element.

More common than you would think.

Honestly, this looks like a BL stamp to me that someone altered. The only way I would ever say this *might* be legit was if it had a correctly dated COPO posi unit and ring and pinion in it and it was in &quot;as found&quot; condition and not painted or fluffed.

Exactly....on the dated COPO R&amp;P portion of the comment.

I am not going to offer opinion either way on the subject rear end. What I will say is that the obliteration marks are consistent with a known manufacturing plant correction technique as recalled to me by the spring and axle line workers.

It is troubling that segments in hobby keep calling most everything with a stamp deviation that does not fit a narrow interpretation fake. If we do this most all of the time we are collectively doomed to learn nothing new before the &quot;living past&quot; transitions into history.

The living past in my statement is in reference to still living line workers who installed these assemblies.

Of course the matter is sealed and left to us to figure out what we can - when remaining workers who can tell us what happened eventually pass away.

That is when this portion of the hobby truly passes into the historical context.

You make a good point Phil. With as many inspections that I do every year it has almost gone the other way. When the stamps look too perfect I start to worry. I wrote off a CRV 3.31 rearend as being a restamp about 2 years ago and actually bought it and put it into my inventory. I thought it was fake as you could clearly see that the face had been hastily ground off and restamped in the stamp area of the axle tube. Fast forward 2 years and I get another LS6 in the shop. While inspecting it I see the same exact thing while forgetting about the other rearend. I was going to write it off as a restamp as well but something kept nagging me. I finally remembered the other rearend and bingo, almost identical and within 5 days of the car in the shop. I conferred with Chris White who also confirmed that he felt it was real. Never say never! This is also why documenting these types of anomalies are so important.
