Default Ford 9" Ring gear question

I have a 9" punkin out of a pickup with the following numbers stamped on the ring gear; C2AW 4210 W

Any idea what the ratio is ? I will count out the teeth, but was curious what the numbers meant. MOPAR stamps the actual ratio on theirs

That's a date code, and case code also manfacture loc. One good thing is that the C2AW stands for a nodular case, it just doesn't have the exra rib and probably not marked with an "N", the gear ratio could be anything depending on what vehicle it came in.
