Shortening Axles- Dana 60 Rear and 44 Front

[69l46vert]

Hi, New here to the 4x4 section. I'm planning on building my 54 GMC into a 4wd. I have axles from a 72 GMC K2500. Dana HD 44 front and Dana 60 rear. These will need to be shortened from approx. 70" WMS-WMS to I think about 60".

What I'm hoping for is to wind up with an axle length that is not a custom length but an off the shelf part. Has anyone here done this or can give me some advice or tips about this? What might some options be?

And what about shortening the rear by cutting off the hub, boring it out to fit the axle shaft and welding it. Is this a bad idea? Thanks, Rick
