Sounds like one side has "push on" retainers and that side is OK. Sounds like you modified the other side's stud to be threaded and used a nut of some kind. The nut came off. So wouldn't you just get another nut like the one that fell off?
Generally speaking Tinnermans are stationary. They are used with a screw that can turn into them. Generally they are not push on.
At this point I don't know if you need a push on or thread on style.
Tinnerman makes a "Pal nut" that threads on and they make an "axle nut" that pushes on. There are other names for these retainers. You will just have to go to a good hardware store with your emblem and play in the toy box.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
