Srt10 Dana 60 swap?

The D60 used in the SRT10 Ram has the larger (3.5"?) diameter axle tubes, and a bunch of other things unique to those trucks. They are wide. I have the measurements off an '05 SRT10 at work. It's wider than the '72-93 truck rears. Not that it couldn't be used, but starting with a more common earlier truck D60 will be easier to narrow and setup for your notch.
