Oil Cooler for 200HP

Hey guys I have a Lycoming IO-360, 200HP and just received an oil cooler I ordered which is the Airflow 2006x 13 row Cooler. It looks big! Any advice on where to mount it? Also, I am in Texas and I had read that I would need a at least a 10 row to keep the engine cool.

Thanks for the wisdom

I used the RV-10 mount and put it on the firewall. Come take a look if you like!
