I was at Dana for a long time, what would you like to know about Dana Axles and Driveshafts! I have a few things laying about, however I know that the older models 25,27,30,41 and 44 all have 2 1/2" outside diameter axle tubes. The I.D changed as load requirement changed. Increases in load capacity requirements changes the I.D. and the models. The outside however is 2 1/2" on all the older stuff model 44 and below.
