Axle width

Ok after talking to the builder about this after I chatted with moser. Moser said the numbers I got have to be wrong. I talked to the builder he is going to look at his blueprint and see if he maybe wrote it down wrong...

Now Moser said if needed provide them with the Housing width and the pinion offset but what is the pinion off set? this is a truck dana housing cut down to fit mopar? axle tubes are 1 3/8ths different to the driver side?
