Exactly. The bolts that go through the caliper bracket into the spindle can be loosened, and sometimes there’s a little bit of play there to adjust the bracket further in.
It’s not much at all, but in your case even a tiny fraction would help.
And BTW, the DoctorDiff stage 1 kit is just OE 73+ Mopar disks. All reproduction factory parts, he just has the rotors made up with the 5x4” bolt pattern. And the hub snout may be a little smaller in diameter than the OE BBP rotors, which may also be why it looks a little longer.
