Post 73 A body. I pulled the steering column no problem. Coupler came off the box no problem. I want to put a new shoe and seal kit on it. The coupler easily slides back and forth on the end of the steering column shaft but stops just as the shoes are flush with the opening of the coupler. What’s keeping the coupler from coming off? I don’t want to force it off and break the shoes. I just need to put a new seal on it. Thanks.
