My right side clip-on broke off a few weeks ago and I ordered the parts to replace it. The only issue I am having is that I can not figure out or find via search, how the piece with the threads that the bar end screws into, gets held in the end of the clip-on. There are no threads, so I wasn't sure if it gets pressed in with some type of hydraulic tool or gets glued in. Any help would be appreciated. Hope my description makes sense.
