ive personally seen the bill...over 9 hours to fit a front diff in sump. We did mine IN the car in under 2 hrs, out of the car its a 1 hour job. 3 hours was charged to clean/degrease sump, baffle plates and oil filter block. Car has the same Hypertune plenumn as your car Russ, was yours a direct fit?, as he was also charged for modifying it and other parts to make it fit...go figure?
