At the Top, Mark. Here is a quick drawing, I'll get some photos later. My plane is an Avid, MKIV, so the original  pedals are by design low mechanical advantage. Your Kitfox is already sweet in that department, from your photos. Note in the photo of my "new" brakes how much closer the pivot point has moved to the pedal, I have about 2.5 times more leverage and therefore more braking power for the same press of my toe brakes.
