I know its not popular but wondering if anyone has knowledge about an o200 oil cooler. I see aircraft spruce has the aero classics 8000075 and the NDM 20002a. What i dont see is the oil filter sandwich adapter. The only place i see this is from stevesaircraft. I'll call them monday but cant believe no one else carries this. They are available for automotive but not sure if size is correct. I kind of want this yesterday.
