The 8.8 rear end in my 1997 GT is making grinding noises. The plan is to rebuild it with 3.73 gears. I am wondering if I should replace the axles or differential too. The plan is get close to 350 wheel HP. Not a daily driver, only street driving.
Here is a pic of the tag on my existing setup. Anyone know what gear ratio it is, does it have 31 spline axles, Posi?
