If the rear was tagged 3.07 then the front is too. Ratios must be the same if your going to even think about using 4wd. If you install the 8.8 and don't have enough cash to readily change the front to match lot of people take out the front driveshaft so even if they do screw up and go into 4hi/4lo they're safe.
And for spirng spacers stay away from stacking them on top of a coil lift. Only time it's really recommended to do that is using a small spacer (usually .75") up front to compensate for a heavier bumper/winch
