These will fit. I would recommend the RB1222Cut for the front and the RB1222 for the rear. Brackets make rear install easier. The custom fit bracket GB756056 or universal bracket, GB758053 work great.
These will work. They will not be custom fit and might require some trimming to get a perfect fit inside the wheel well.
They will attach with self tapping screws to the lip of the fender.
these flaps would work on the rear wheels, and i would recommend the bracket, GB755021
For the front the RB1222CutSS would work on the front and no bracket would be needed.
The plates on the Razorbacks cannot be removed. They are embedded in the rubber. The Gatorback flaps have plates that can be removed, you can find those here, https://www.sharptruck.com/mud-flaps
