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

I read that thread too and missed that part! I'm in az and it's going on 8 days no rotors yet. Hopefully they come soon. I got impatient and tried cobra rotors from auto zone, they held the caliper about 3/8 inch from the adaptor bracket mounted on the spindle.

Yeah they're Corvette C4 rotors re-drilled to 5x4.5".

As I remember it was a few days before the rotors even shipped, they're made to order.
