Dana 60 - Pinion depth problem

have a question, i just received my axles from Strange and noticed that the invoice shows both left and right axles to be the same length, sure enough they are the same. Am i crazy but i thought there is a left and right for dana 60 axles. The rear was cut and measured, Drivers side tube (flange to pinion center) is 23 1/2 while passenger side tube measurement is (flange to pinion center) 22 1/2. I would have thought the axles would be 1" different. Housing end to end is 46". Any thoughts? thanks. Strange is closed so maybe i need to call them on Monday
