Earliest 3969341 and Latest 3894860 axles

Just drug this out of a barn in Indiana this afternoon. The "C" has been peened over, guessing at the factory. This axle has never had the numbers area cleaned off till I bought it. Will get a better pic of Cast Date tomorrow. Looks like F119 (June 11th)?

funny how out of small sample now 3 guys have "penned" or debris marks where the C would have been. (insert conspiracy theory here)

... I noticed this also...  makes me wonder if the factory workers (either in the differential plant, OR at auto assembly (for the late '69 series rears, did that on purpose to eliminate (or try to eliminate) the discrepancy between '69 and '70 part assembly codes (ie. 70's got the 'C' in front)...??

08E,9N677163 has an 341 axle with a code of CBL0812G2. Can't read the casting date. Too crusty from oil...Joe

[BULLITT65]

Interesting. I have an original BU 0815 G2. No C, and I have also found an original BS 0822 G2, again no C on either and no marks on either where a C could have been. Only similar thing I have noticed is they were both made 2nd shift on a Friday. (1 week apart).

Can you post a pic of the axel stamp?

[ko-lek-tor]

Clearer pictures of rear I posted on the 22nd. I erred in the cast date of May (F). It is in fact (I) Sept. makes sense. More current pics

Bentley,
Can I get a job with you? You seem to have time to do fun things.

[bcmiller]

Thanks for the additional information everyone.  I will get the data updated and post below.

Joe, does the casting number on the center housing end in 341 or 860?  And what is the casting date?

Austin, can you post good pics of the other stamp you have without the C please?   Thanks

I just noticed another CBU0829G1 axle. Just like Gary's, the C is peened out (completely!).
9N684457  09C

And another - CBU0929G1 10A car - pic doesn't show all the C, but the area is peened.

I theorize that axles were built and in racks ready to deliver for the Camaro/Nova line. Because the Camaro line was held over, considered a 69 by Norwood brass? a directive came from Norwood that said they did not want that C on the axle, so shipments slated for Norwood had to be manually gone through by a worker at Eaton? or Norwood? and correct them to what Norwood wanted to show as a 69 axle maybe for warranty or some other accounting reason? Some, made it through because for the same reason other discrepancies exist.   

[BULLITT65]

How dare you say there were discrepancies!!!

Don't hint that the facts have a variation, you run the risk of your data not being used....hahaha
