No problem Bryon - any idea why this date was on opposite side of the 860 casting location where the foundry stamp would be. And as a follow-up to my thread, where is the 341 casting number?  We can't find it in the spot where they are on the 860s.

Rob, if the axle is installed in the car - the casting date is normally in the vertical "webbing" area on the top left or top right of the center section.  You will see it looking from the back of the car forward.  May not been in exactly the same place on every axle.

Casting number is normally on the front part of the lower "webbing" on the drivers side.  See this pic.

Edit:  To clarify wording and add back photo.

Bryon - the casting date was opposite side on passenger side where pics show foundry to be. But those pics reference an 860 casting and not 341. Darell and I did an extensive search and never found the casting number in the place it should be. Is it possible it wore off...jerry has it in the report. Thinking with these 341s that they, like the cast date, may be opposite side or different spot altogether.

Found a Google image of location and just found it 3969341NF...driver side of lower pumpkin facing forward. Maybe you have a new note...casting number location and casting date on 341s not in same location as 860s?  At least based on my location and the pics on this site of the 860s

Because of the circumstances, this probably doesn't help you much.
3
41 Cast F 28 9

No assembly code, and never had one.

My car is an 08A car, 671122.  I do not believe the axle is original to the car for several reasons.

Thanks Lynn.  Yes I do remember talking about your housing, which is probably a service replacement. 

Actually the casting date for the 341 housing does help.  The latest 860 housing we have so far has a casting date of F 24 9 (which has a 3 letter ratio code) and your 341 housing is only 4 days later than that.

I am curious, of those that have the "C" stamping on there rear end, does anybody have the protecto plate showing the "C" as well?

I don't think you will find that on any POPs.

And for what it is worth, I have a pic of a 1970 Chevelle POP.  Axle assembly date is September and the engine assembly date is November.  The engine code and the axle code on the POP are both 2 letter codes.

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 another piece of info that you may want keep as a side note is John Berry's 08A car has a correctly dated rear end with the original axel tubes, but does not have any stamp present. I know originally it was thought that it was a replacement that happen to fit date wise, but maybe the time frame of early August of 69 there was something weird going on with the rear end stamping process? It would be nice to find more cars between his and mine that have there original rear end stamp. :)

I did not know this about John Berry's  Z.  It is same week (08A) and only 86 numbers after my car.   I know of several similarities, and talked with John back in the 90's when he still owned the car.  I am curious how certain it is that the rear is original.  Seems strange that are cars are that close and NEITHER of them has the assembly stamp.   I have always just assumed mine was replaced.

Lynn, have you checked both axle tubes to see if the stamp might be somewhere other than the typical location?
