I don't think there is any question, this
] is what you need. I have replaced them on TF. Drill out/shave head or otherwise remove old rivet. Install roller and rivet and swage over/upset rivet. The swage over is a little sketchy. The rivet is hollow on that end. I used a tapered tool. The wall of the hollow will probably split. Then also want to lean to one side or the other if I remember. I hit it down some with a hammer/flat punch too. It did not look too nice after I was done, but it was "riveted". If I do it again, I may saw the "X" and "Y" axis of the wall to create 4 "tabs" to bend over. Not sure til I try that. You may want to buy two sets.
If you are concerned about 1/4 or 5/16, remove the rivet and check the hole. You don't want a 1/4 in a 5/16 hole.
