Please help me id this steering column part

Chrysler called that part a bumper #3575257. It was used on most steering columns with floor shift from 1971 thru 1976. Go to mymopar and download the 1973 dodge chassis service manual. On page 19-50 there is a picture of the bumper and a description of its function. It is great to have the service manuals available online,but the photos are a bit clearer in the original paper manuals.
