broken shifter jam

[striperman36]

in the throttle control there is a small black piece that holds the motor cable hosing in place so the cable inside can move freely.
Mine has some how broken into pieces. I thought the shifter was stiff last year and I took it apart this spring to lube the interior.
I did not notice this missing component until I tried to shift into gear,
Oops.
Can someone tell me if this piece the you can purchase somewhere?
The cable when disconnected from the shifter and the shifter lever on the engine seems to move smoothly.

I also made sure I lubed the shifter bar but I am unable to shift the motor manually into gear while I spin the prop. Is this normal?

Thanks,
Bill
