Today I finished the mod to the quarter window where I installed a NACA duct with a three inch exit. This will provide air to a cooler for the diff.
This was not an easy task as this NACA duct is pretty large for the available area and glass size.
Since I installed a full belly pan I believe I must deal with the heat the diff develops and that the airflow to it has been hampered by the pan. The oil cooler is part of the solution.
More pics to follow as I install the pump and cooler.
