Who knows about rear-end gears?

This is pretty much what you are gonna hear on this board.
An auto usually the 3.80, a manual would get a 4.10 ratio.

Personally, if it were my car and I was not gonna see a lot of highway miles, I would go higher with the 4.10 whether the car was amanual or auto.

If your engine makes a lot of power, but you only have a 3 speed auto or an older 4 speed stick, you could probably get by with the 3.80 and still have a decent cruising rpm.
