I'm pretty sure it works this way

The lower the numerical value, the better gas-mileage and streetability. Example being 3.55's would provide you with MUCH better gas mileage, and driveability on the street and highway, as compared to some 4.10's, but 4.10's aren't very high-way friendly, lower gas mileage, but a much faster launch.

Get it?

I'm not sure what differential gears the newer mustangs come with stock, I'm sure 3.55's is a good guess though. Yes, any mustang, any model, any car and make can install different gears in their differential.

In terms of bang for your back, this is a great modification to do, depending on what you want, if you want performance, but still want a daily driver than 3.73's are a good route to go, if you're looking at total performance, 4.10's are king.

good gas mileage and driveability would be 3.55's and lower

Cool, in my case gas mileage, because my car with the automatic transmission is making only 207 miles with full tank, almost 15 mpg only, thats crazy... ehehe...
