‘71 340 Duster Front Drum to Disk with Factory 14” Rallye Wheels - Problems

i'll throw another log on the fire: does that rotor look weird to anybody else? like the snout of it is way long? maybe there's a manufacturing defect and it was cast incorrectly and the face of the rotor is supposed to be 1/2" further out?

but a +1 to aftermarket wheels maybe playing a role, and another +1 to tolerance stack and giving the caliper brackets the ol' loosey-goosey and a shimmy shake before taking a soft wheel to them.
