Part ID-Steering column parts and trans-shifter linkages

[Snowdog]

Can you guys help me out on IDs on a couple of parts? I know the two black round parts are from a steering column part that goes under the steering wheel, I just can't figure out what vehicle. The smaller aluminum round part I have no clue. Also, I can't remember what this little link is for, it might be for this old Mr. Gasket inline shifter I have, but the pin doesn't quite fit the shifter levers. It's the little one at the bottom of the pic with the other linkages.

Any help would be appreciated, Thanks!

Thanks, yep that makes sense. I don't know why I didn't of that, maybe because it was 40 years ago when I pulled that engine apart. I think I better get an engine rebuilding book.
