Hey guys, i just got some time to finally do this conversion and i have a small question: Are the cable stops supposed to secure the housing tightly when everything is screwed tight? or is it just supposed hold the housing in place, and when everything is wired together, it will just stay in just fine?

I assumed that the cable stops would just lock on tight to the housing when i screw it tight, but that wasnt the case. And I thought that i bought the wrong size, since the width of my housing is 4mm
