Can anyone out there help with a 12 bolt rearend I recently picked up. The numbers stamped on the axle tube are: BM 0122 G1

I'm not sure if it is from a Camaro/Nova as the spring perches have been removed - but there are not any bushing eyes on the differential itself, so I assumed it was from a leaf spring car???

Thanks!

The 0122 is January 22nd. The BM, according to my book, is a 68/69 Nova or 69 Camaro non-posi with 3:31 gear ratio. The G is Detroit Gear and Axle.
