Barracuda fender clearance for wide tires

Hi, I have an RMS suspension and 275's up front on my '67 Barracuda. I need to make some clearance for the tire in the front of the wheel well as it touches the bottom of the fender when turning. I'm sure there is a good way to do this, could anyone share some methods?

In the picture, I think everything between the tape and wheel needs to be trimmed, but I want to keep the part the wheel molding mounts to for strength and molding.

Thanks,
Steve
