That's a heavy dooty posi unit...good deal!
Cars assembled after August '69 supposedly used the '70 axle codes....which for your car would be
CAZ. Not sure why your diff has the "1" on it....could simply be an anomaly, or the guy in charge of stamping that day had a hangover....who knows....
The "1" is stamped a wee bit off-kilter, so my guess is it was stamped AFTER the rest of the axle code was stamped.
