Questions on Dr. Diff 13" Cobra Style front brake setup

if you look at the last picture I attached, it shows the bolt that goes through the adapter bracket, into the caliper. It will hit the spindle if you try to take it out. I can get around it by putting the bolt loosely in the hole,, and then attaching the adapter bracket to the spindle. I will just put the caliper on with the rotor, as one. not sure if that makes sense, or if I have something else not done correctly but that bolt most definitely is hitting the spindle.

I have the A body spindles.

Thanks for your reply, Im looking forward to getting the rotors!
