I had to go out and get some bolts to mock these parts up. I have had them for some time now, and have never put them together to see how thing would line up.
I was going to tell you the rotor does not have to be centered perfectly. The two pistons in the caliper will move the pads out touch and the fluid pressure will equalize and the pistons will be pushing against each other.

Picture shows how rotor is aligned in caliper
With this picture you should be able to put your wheel on, and get an idea if you wil have o bend the steering arm to clear the wheel.
