Casting number 860NF
Assembly stamp BU 1126 G1 E
Casting date K228

Casting and assembly date look fine and thanks for submitting. Is that the original axle for your car? If so, we may want to document it more. That is a fairly large spread from axle assembly to your car assembly but it is possible. Would you happen to have the Protect-o-Plate for your car?

The thread is mostly concerned with the time frame of axles cast or assembled from about May of 69 through the end of the model year.

The CHP report for the car states that he has seen late build examples with rear axle stamps with 5 months spread, and could not say for certain the axle is original to car but was possible. He did certify that the axle stamps are legitimate and not re-stamps and the car was born with 12 bolt. I do not have the POP for the car.

That’s a 7 month spread. Possible. Just wondered if there was solid proof, because it’s a potential area to learn.

Yea I know its a stretch but I offered it as a possible data point.

It's not original. Axles were very tight in early 69. There is one 06A car in the database with an axle that is in March (and not a common axle code). All the rest are May / June axles.

I am still EXPLORING the thinking

"trying to clear out parts toward the end of the model year, because the system was not a first in / first out setup."


Not saying that is the case....

[boomer632]

As I said Im just going by what JM stated in report.. only offering data

[bcmiller]

Not a 12 bolt, but a late 69 model year 10 bolt using the 3 letter code convention.

My 09C has H59 casting date and C BU 0814G1 stamp.

Fixed!

[bcmiller]

Thanks! I will add it to the list.

Please when submitting data - put all of the information requested in ONE POST - PLEASE.

Some notations have been made for C BU axles where the C has been peened. I did not note this on all of the ones listed.

Here is what we have so far.  We need more data points for axle assembly dates between early June and early August.  My apologies if your data was inadvertently missed.

It appears that the 341 casting number started being used in June. It appears that the 3 letter code had started by early August, possibly earlier.

Remember that there was a shutdown for the latter part of July and into very early August.
