I am going to try to summarize what we have so far and put into one post.

Sorry, my rear end is in the car. I tried to get off some undercoating and wire brush it, and while I can "see" it I can't get the camera at the right angle to capture it. I can try again in a few days when I am by the car again.

OK, I went through what we have so far and tried to put them in order.  It is more difficult to put the data together if everything is not in one post.  Let me know if you see errors.

Looks like we have at least a few days of overlap of the housings used in early August at the axle assembly plants. Not surprising.

That's fine. I am trying to look at the data right now by assembly date stamp.

And I can go back to modify my posts.   Smiley

In my humble opinion, that would not be unusual.  There is almost always some overlap.

For example, on the weekend I saw Muncie M20 assembled in August of 1969, with a 1970 VIN on it (I think for a Buick).  It had the 660 case but with both a drain and a fill plug - and used the 1970 style plugs.

How is that unusual Bryon?   An August '69 Muncie trans for a Buick would be going into a '70 model Buick wouldn't it?   Typically model changeover during those days was July for the transition, and by late July and August they are building for the new model year..

Gary, on the transmission, Yes, an August of 69 assembly sure could go into an early 70 Buick. No issue there.

There is some overlap on the 3925660 and 3925661 cases early in the 1970 model year (and in the extended 1969 Camaro production).  

The anomaly is that from what I have seen, any 3925660 cases used early in the 1970 model year with both a fill and drain plug were M22s.  The one I saw was definitely an M20 and it appeared to be all original, with both an original fill plug and an original drain plug.  

All 3925661 cases that I have seen had a fill plug and a drain plug.

sorry just noticed this thread.  Here is a pic of mine from a 08C ( August of 69) car.

This stamping looks anomalous.  I have consulted with others, so it is not just my opinion.  Sorry.

It also does not appear to fit well in the 2 letter / 3 letter code data.  I am going to modify my list of summarized data in the previous post above.  

Any late July or early August axle assembly data (plus casting number and casting date) will be greatly appreciated.  Post pics if possible.

Austin,
The axle stamp does not appear to be like other typical stamps that we have seen due to spacing. I know a lot of the history of your car is known, but it is not a typical stamp.
To help reduce possible distortion of the data, it will not be included with the other data gathered until other stamp photos corroborate it as a production anomaly.
Thanks!

Kurt,

Thanks for putting those threads back in and for *improving* some of the wording... Smiley 
.. maybe you can give Bullitt an opportunity to 'reword' some of his original post(s) - eliminate use of the word 'ethics' from the title and text and perhaps improve some of HIS OWN wording - now that he's had a week to think about things...?   Smiley

(I'll be away this week for the CNA convention, but I wanted to Thank You first for trying to cool down some of the heat, and to Thank Ed Bertrand publicly for all his contributions and help in the past..... Smiley

Hope this helps.
Here is my 07A X77 rear stamping and casting date photos. With the Norwood factory shutting down July 11th and not starting up again until August 11th I think my car would have been one of the last Z's built before the shutdown. My NCRS production date was July 10th.

VIN 9N6687XX
BU 0630 G2
E 26 9 casting date

Interesting. So the cars that are 7A or 8A were they the cars that they assembled out of the rest of the parts that were on hand, until production started back up?
