Fender Trimming for 33s w/ 3.5" BS

I recently installed a set of 285/75/16 AT tires on 16x8 wheels with 3.5” backspacing. I actually ordered wheels with 4.5” backspacing but I was sent the wrong ones and chose to keep them because I got a huge discount on them.

I’m trying to figure out the best way to trim my fenders to eliminate rubbing. I already removed the fender flares to make the truck drivable on the street. It is hard for me to know exactly how much I will need to trim at full lock because I have just driven it on pavement. I have an aftermarket bumper so there is no issue with that side of the front wheel wells.

Will I need to cut around the entire perimeter of the fenders such as done in this thread:

If I use a jigsaw to cut the steel fenders around the entire border and a razor around the fender flare, should I worry remounting the plastic inner fender well?

Should I just worry about the back of the front fender? Will I need to trim the back fenders as well?

I attached some pictures so you can get an idea of how its looking now..

Any suggestions would be much appreciated!!
