Gears

[Bobus]

So I just bought a '07 F350 4x4 Dually auto with 97k miles. I notice that running 75mph I'm turning 23/2400 RPM. So I crawled under and found I have 4.10 gears. I want 3.73s can I swap a set gears from a '01 SRW axles into my dually axles or do I need gears from a dually axle to go into a dually axle? Or just buy new gears?
