BOM location on a Dana 60 or 70

[invno1]

Hey guys,

I'm sure this has been asked before many times, but i'm gonna ask anyway.

I'm trying to find the BOM on the rear axle(s) I have here. I'm not sure if they are Dana 60s or 70s. One is out of a 91 3+3 quad cab, and the other out of an 80 or 81 reg cab diesel dually.

I thought they would be in the same relative location (on the right hand side tube of the diff while looking at the diff cover) as the front 60 but I have not been able to find them. The only numbers I found on the right side tube where HHW 61063 and KMU 02532 (or something close to that can't recall exactly.

Any help would be great.

Thanks.
