I have researched the site and novaresoure site also. But can't find this rear end code. Appears to be a post 70 chevelle or similar rear design, no leaf springs, with the eyes at top and arm mounts. Its an 8.5 posi, drum brakes, about 61-61 1/2"" drum to drum. axle tube code ACC6135 1/
On the center section 1234774. Thanks.

I show there is an AC used for the mid 70's (73+)chevelle with 2.73 ratio
The other C should be the axle plant.

Thanks. On the casing also is K14. Would this be Nov 1 1974? BTW this is a 4 link.
