[Ol' Chevy]

Howdy,
I'm getting ready to swap out the original axles under my pickup for a Dana 60 (rear) and a Dana 44 (front). Currently the rig has 4.56:1 gears in it. The Dana 60 I'm buying has 4.10's, and I think I have a lead on a Dana 44 with 4.10's. I'm expecting a little quieter ride, and hoping for a boost in gas mileage. Is anyone running 4.10's with stock tires, and if so, would you reccomend that gear ratio, or would I get significantly better gas mileage with 3.73 gears? The reason behind the 4.10's is mostly availability. No yards around here have 3/4 ton diff's with 3.73's
