Stop in for a cup of coffee

So found a slight hiccup on my dart today. The center hub bore of the rotors, mustang II, are 70.3 mm by spec. The rims I ordered for this are spec’d to 70.6mm. Should clear right, nope. The wheels center bore tapers down from 70.6 to 70mm. Rotor center hub bottoms out about 1/4 inch from the edge. So I’m gonna have to find a place to turn down my rotors a little bit.
