You have the engine mounted oil cooler. It can't replace the trombone. You already have one attached to the engine case.

look closely and you will see that the I and II are not part of the cooler--its the supply line from the oil tank to the pump .The in and out ports are III and IIII [actually the top of the cooler.] How will you mount it to get airflow?
