Title: Rear End identification
Post by: munch on September 01, 2019, 04:29:59 PM

I have a GM rear end that has a code N 3894859 and it is a 10 bolt. From what I can find, it appears to be a 67 -69.  Looking at the front of the unit, there is a GM9 stamp on the upper right and on the passenger axle housing is BA09 22 W.

Can anyone give me more detail?

Thanks

If GM9 is the RPO Code: I found this:

GM9 8244 P RAX M AXLE REAR 3.63 RATIO 10521 E X E A
