For trucks at least, the axle ratio coding is contained in 'Position 9' of the VIN number. This sticker should be on the door jamb of the vehicle. You'll need some sort of decoder like this:

Not sure if above decoder is also applicable to vans - you may have to do some searching on the 'net. You could always call a local Ford dealer with the VIN number and they should be able to tell you the Axle Ratio that was used when the vehicle was manufactured. It is very unlikely that a prior owner would change out rear axle gearing. Never heard of a 2.73 axle - are you sure it wan't 3.73?
