I was wondering if this is a 65 or 66 12-bolt? the casting date # is A 11 5 and it is stamped CW0127 thanks, Stan

I believe that would be a 1965 12 bolt 3.31:1 non-posi.

By the casting date I would say 1965 also. The casting number on the center section is 3859140 for 1965 and 3875745 for a 1966 12-bolt.

Great, I was hoping it was 65 as it came with the pile of parts with my 65 elcamino. The original owner said it is the original rear with a broken pinion.

Thanks, Stan
