I have the billet oil cooler, but I didn't have that problem. It has a stock frame so far. Could your frame be closer to the motor than stock. Mine bolted on easy. Here is a picture of how mine is set up. That is before I installed the TB head kit. I didn't have to relocate the cooler though. I will have to make my own brackets when I get my Perimeter frame, but with stock one it bolted on no problems. Maybe the picture will help.
