if your current shaft is the balloon style ends were it shrinks down to the yokes then you can not reuse them much at all . there more a 1 and done .

now if the newer one or your older one are just std tube the same dia all the way from one yoke to the other no problem . this will be easy for a driveline shop to work with .

i would also grab the rear yoke at a bare minimum for the nv3500 just to know 100% you have a yoke that fits the trans your getting .

and only have the shaft made up / modified once all your mods are done and sitting on ride height . this way you can measure for angles of yokes and length of the shaft .

3 pics i saved from doing my rear shaft on my current 4x4 build .
