2021 Sierra Mudflap rubbing

[Phildosaurus]

I’m running 275/65/r20 with a 1.5” bilstein level and 1.5” hub adapters. I have trimmed the flaps and done some pulling back of the fender liners with zip ties, but I still get some rub at the innermost screw for the mudflaps.
 

Looking for ideas that don’t involve cutting into the body and only leaving two points of attachment for the flaps. I’m tempted to get out the mallet and see if I can roll that corner back a bit… curious to hear how others have solved this one.

Update: I grew impatient and went the brute force route. Got the heat gun and deadblow out and that corner rolled back super easily. I bet I gained a 1/2” or more with a couple of thumps and now everything clears nicely.
