Nobody?

This unit is from Nov. 11 1968 assembled rear .

Thanks! That confirms I was used for the year.

I bought a May of 67 complete original rear end yesterday and it had H for the year.

So it looks like H for 67, I for 68, J for 69. Thanks everybody!

There is the I. So I was used. So F wold be '65, G '66, H '67, I '68 and J '69. I wonder if K, L and M were '70, '71 and '72?

I wonder too. Hopefully we can get more data points.

So what is D 3 A?.....April 3, 1973
I have one with this stamp.

However, it has a casted date on the side of "40" (February 9) and I thought that was the only date.

I have another one with this stamp. B 1 G " Feb 1, 1966?

It has a casted date on the side of "24" (January 24)

Thanks for posting. Is it in an original rear end?

The only way to really verify dates is if it would be a complete original assembly.

If it's a 12 bolt Eaton with a '73 date then it would not be an assembly line unit because the 12 bolt was not used after '72.

The two that I have listed are loose units that I have lying around, so I don't know what they are out of or the actual date.

I was requesting assistance with the stamped date for the cast dates I know how to read.
