Would or Wouldnt cut

I would like to be able to fit 15x8 drag radials in my rear wheel well of 71 Scamp. The 1/2" lip on the inside of the wheel well that the chrome trim would screwed to is in the way. I dont have the chrome trim on my car, so this lip is not needed, but wondering about the strength if I remove that lip. My axle is centered under the car and I have a equal amount of space on both sides.

What would you guys do? Cut it off, leave it, or do something else? If you choose do something else please give me your ideas. Thanks
