This is the axle code from my 72 elky

GDC 012 2E

Can anybody tell me what it should be>

Thanks!!!

4XL your axle code is a 2.73:1 posi assembled at the buffalo plant on Jan 12 1972 on the 2nd shift.

Thanks!

Looks like the origional rear!!! It does have a 2.73 and the posi still.

To bad it's not an 8.5 like I thought I had. The gear is in pretty bad shape.
