Sorry no pics, but some numbers.

I've been told it's a mopar car dana, that has found it's way into a chevy.

Here are the numbers(second hand, I still haven't seen the unit)

BOM# 602829-2
Date code 11 30 6c2

That's a copy and paste, so any typo's aren't mine
Thanks

Chart doesn't go old enough.

Going by what it says, The housing is date coded late 66, but there's no reference to the bom #'s on that chart.

Any other charts out there?

None of my Dana info goes back that far. What is the bolt pattern on the axles? Other than Ford and AMC, I would think a 5 on 4 1/2 would indicate a Chrysler application. (Not implying Ford or AMC used Dana's in the automobile line).

If the rear has a pinion snubber provision, that date code would indicate a '67 B-body unit with 3.54 powerlock.

Unfortunately, I'm at home, so I can't check any early BOM numbers.
