The oil coolers are extremely fragile. I would not attempt the cutting and tapping of one myself and I am an advanced hobbiest. I would recommend getting a good used cooler. be sure to use the second wrench when installing or removing lines on the cooler as you will twist off the fitting and ruin it in a heartbeat if you don't.
