They should have their own machined bolt to fit in the slotted hole. Terrible camber adjustment on the cup 60mm fitting racelands as they are drilled out, think this is slightly different to the 172 though.
Ktec stock these and their own set which is very very very very very very* (*I could keep going) similar. I would have thought that they cold help you out.
Edit. Completely misread the fact you mention KTEC in thread title, so you are clearly aware of the similarities and my post above is now rather pointless lol.
