I'm new to small blocks, what is the part in the yellow circle? Thanks!:o

4 speed shaft

Pivot ball that the Z-bar pivots on for the clutch.

As mentioned it is a cross shaft or Z-bar pivot for the clutch linkage.

thanks guys! I should have looked back through my pictures from before the engine was removed, I may have seen that. But I did take a look at my z bar and I now see how it all goes together. I am labeling everything as I remove it. Thanks again!
