Steering Column bearing-71 Challenger

[71ChallyRT]

I looked through all of the previous posts regarding these bearings and I didn't really see a definitive answer. Found two different items at Classic Industries( pictures attached) and I called their tech support and they stated I needed to use both. At this point, the simple plastic device was "hanging out" on the steering shaft but not inside the column like to should have been and no dust cover present. The other device (with bearing inside) is not present in my column and I don't see any holes where the screws would be installed to hold it. Anyone know for sure?
Thanks All!
