I agree that axle swap is easier; with this caveat, you need to locate axles that you think you can drop in. For me, it turned out to be an exercise in futility. All axles I looked at were dubious and I figured I would have to rebuild anyway. So, it's a tough call. If you locate what you think are good axles in your time frame then great. But if you cannot and you want to move the ball forward then you may need to take on the gear swap or buy take outs from know source.

It's a double edged kind of a deal!

I say 3.73 or 4.10 it's a truck!
