Tech Article - First Generation Chevy Camaro Suspension Upgrade

Hello,
I am curious if anyone out there may be able to enlighten me on the big-brake installation in the Tech Article called "First Generation Chevy Camaro Suspension Upgrade - Subframe To Surface Missle."

I too have a Chassisworks "Street Machine" front suspension, and am now looking to buy brakes for it.  The main issue I have is that they only sell "their" kit, which does not come coated or cross-drilled, and is only 11.75" in diameter.  This is the first/only article I have seen that shows installation of a big-brake kit, but says nothing about how the calipers were mounted on the Chassisworks spindle.

How was the caliper mounted to the Chassisworks pad-mount on the spindle, what Wilwood brake kit was used, and were there any one-off brackets that had to be made to fit those 13" rotors?  A picture of the mounted-assembly from the back would be great!  Thanks
Kyle
