Bushing or not?

Not really. My '69 Dart has an all steel bearing that I got with my Gerst front suspension. The orginal was a plastic bearing? Carl sold out to QA 1, don't know if they might carry it. Or Mega parts has steering column parts, might give them a call.

The originals for the manual steering floor shift cars was a metal bearing in a plastic bushing/adapter, like I linked above.

Yours just looks like an ER16 like in my how-to, which is like a $10 generic bearing that’s commercially available.
