Distributor drives are of two types.

The original type has about a 5" shaft which is placed loosely between the distributor bevel gear housing coupler and the bottom coupler of the distributor. It has only a "slot" at each end to match the "tang" at the bevel gear housing and distributor bottom. The slot/tang is oriented slightly off center which is how the timing/shaft positioning is kept from being inadvertently misplaced 180 degrees when the distributor is removed or replaced during servicing.

The aftermarket type has but a single shaft (no loose piece) with a collar instead of a coupler and goes down "deep" inside the engine block and contacts the top coupler of the bevel gear drive directly. Like the original version above, it relies on an off center slot/tang to preserve timing.

This sounding like original. As the distributor was removed, it left the short piece behind in the block. (that if you don't see an extended shaft from the bottom of the distributor.)

There has been discussions of the disadvantages/merits of both of these here on this board. In practicality they work pretty much the same.
