I have the J55 RPO, but pretty sure I have the 12" rotors installed

Need to replace the front rotors/pads/calipers, as I had the car pull to one side during a recent drive. Only happened once, but this kind of issue won't just magically go away.

Looking at my RPO codes, I see J55 listed, which are the heavy duty brakes. Everything I've read, this means it includes the 13" rotors in the front. But I think this car has had the rotors replaced with standard 12" rotors. Pic below of my wheel for reference. Please don't judge too much for the dirty car.

If I go to replace everything with the J55 stuff, do the caliper brackets line up, or are things different? Suspension codes are FE1 and FX3, so I do not have the HD suspension.

I knew I was having a heck of a time finding the right parts for some reason, and if the HD rotors were replaced with standard rotors, this would make sense.
