Earliest 3969341 and Latest 3894860 axles
« on: January 09, 2013, 03:48:08 AM »
It appears that 12 bolt rear axles with casting number 3969341 started showing up in 69 Camaros sometime around early August of 1969.  Prior to this, only the 3894860 casting number was used.  

What I am looking for are dates (casting date of housing and assembly date stamp - with letter codes - on the axle tube) for early 3969341 axles and late 3894860 axles.  If you know it is original to the car, you can post the body assembly date from the cowl tag too.

Please let me know what you have.  Post pics if possible.  There was probably somewhat of an overlap, but not sure how much.    

Thanks in advance!

I parted out 9N677954  CBS0805G  341, cast G259. I only know of 2 341's before that one. There have to be more.....

Not a lot of axle casting data on these late cars in the db.

Gary

Gary, is it stamped BU or CBU?  The one Kurt posted had a casting date earlier than yours and it used the 3 letter code. 

I am just trying to see if maybe the casting date change corresponded with the change from 2 letter codes to 3 letter codes.

That looks like a C to the left of the BU. Pretty hard to see...

..  then you have better eyes or a better imagination than I, Kurt..  :)
Do you have a photo of a CBU stamp?  I don't think I've ever seen one, so maybe it's not like I was expecting..?
or maybe Bryon can post a pix of his as he has a C BU code??
