I Set the Mustang's Pinion Angle

After several updates to the Mustang, driving at higher speeds revealed a vibration coming from the driveline. The issue is that the engine slopes down 4 degrees but the pinion of the differential is sloping upwards 6 degrees. The pinion's angle should be just under the 4 degrees to allow a slight rise when torque is sent to the rear axle because that will cause the pinion to raise to near perfect angle and spin smooth as glass.

Orange copper RTV on the exhaust, no gasket. Trust me.

I’m going to try one more thing before the copper, promise
