I bought a whole AP Racing CP5555 6pot F/4pot R BBK from one of our fellow forum members (great guy and really helped me out). He had this kit on his C5Z as well. I finally got some new wheels to house my AP Racing BBK setup, and I can't seem to figure out how to mount the caliper to the knuckle!

The calipers mounts to the included L brackets just fine. However, I can't figure out how the heck the L bracket mounts on the knuckle. Both have smooth bored holes in them, so there's no where for the GM OEM caliper mounting screw to screw into. Am I missing a part, or have I just not figured out the magic way to do this?

I can't seem to find any info online about installing this kit, so I'm scouring for similar kit install vids/pics and trying to piece things together. I don't believe they make this exact caliper anymore, but they still support it.

Here's an example of what I found for mounting an AP Racing kit on a 370z:

Particularly, this L bracket in these two pics:

"Install the bracket reusing the 22mm bolts from the factory caliper with some red loctite on the threads. Torque to between 70-80 lb/ft."

How in the heck does that L bracket mount on the knuckle on my C5Z with only smooth bored holes on both parts? There's not enough thread left for a nut on the other end either.
