Differential decode help

[Donald H.]

This differential is in a 66, but clearly not original or from 66. I think I have decoded it. Help please!

housing stamping is:

OM 062 W9E1

I think:
OM is 78 or 79 Posi 3:36
062 is Julian date March 3rd

W is that Warren
9 is that 1979
E1 is Eaton and first shift

Is any or all of this correct?

Thanks,
Don
