What does the lower steering column bearing or bushing look like for a floor shift car? I converted this over from column shift and I’m not sure what holds the shaft in the center of the column housing at the bottom.

Like on the e body there is a snap ring that retains a plastic bushing. Or some of them take a bushing with 2 or 3 screws around the perimeter. This has no holes or slots, completely smooth. Unlike the earlier cars with a one piece steering shaft omitting this bushing is no big deal. With the later 2 piece shaft this won't fly. What an I missing? Year one lists various part numbers for 73 and down b body.
