Without a lot more detail on your engine, transmission and tire choices in addition to how you plan to load and use the truck, this would be a hard call to make.
I chose to put a 14-bolt with 3.42 gears under my 1-ton project and those gears where part of the decision, but just because its right for me doesn't make it right for you.
Are you sure you're dealing with a Dana 60? I don't think the Dana looks that much different than the GM axle so that consideration doesn't make sense to me.
However I have two Dana 70HD axles that are under or from GM trucks, so I would not hesitate to use a Dana under your truck.
