Steering Gear! Is this supposed to have a cap over the spline?

All: Putting the front end back together on my 300 drop top, and looking at my steering gear and universal. As per a 13 year lay off, I have plastic tubs of parts all over my garage and wondering if I am missing something. Is there supposed to be a cap over the spline that connects the steering column universal to the spline on the steering gear? See photos. View attachment 420043
