69 SS Axle Codes

[boomer632]

Car is a 69 X66 with L78 motor and M22 with 12 bolt posi

Axle is stamped BU 1126 G1
                                 E

Which translates to 3.73 assembled 11/26 1968 Detroit Gear 1st shift with Eaton Posi

Casting date code on housing is K 22 8 which is Nov 11 1968
Casting Code on housing is 3894860NF

My trim tag is 06A with NCRS shipping date of 6/16/69

Is it safe to assume my axle is not original due to the lapse in time from body date and axle build dates?

Thanks in advance.

I would not assume that.  Keep it and look for a date closer as you never know your paperwork might show up at some point.

I'm 99.999 percent sure it's not original. All the BU axles we have in the database during the 06A time frame for Norwood (approx 35) are dated mid May to early June, 1969.
