I did the OEM upgrade as well and fought those bolts also. Soaking with PB Blaster did the trick. My bolts got messed up before I learned of PB Blaster. So I had to pick up some new ones at the dealer. They already come with the red loctite on them.
Try the air design fender flares. They are more fitting for the lowered style truck. They are available as a ford accessory (best way to get a discount).
You cannot get the parts unless you have a Shelby truck. They check the ownership against the VIN and there is an authentication process before they’ll send the parts. They don’t want people knocking them off. Kinda stupid since you can literally buy parts a la carte for the Mustang.

In case you just decide to upgrade the door speakers only; I spoke with Crutchfield support, and they said their research recommends against using an aftermarket tweeter unless you bypass the factory one. According to them, replacing the OEM tweeter while keeping it connected to the factory...
How is this any different than what is already offered by CSS? Other than supplying the clock spring and steering wheel.
