If you are talking about the plastic gear at the end of the cable that links to the shaft gear,I think it should be part #9775187,lite Blue,45 teeth,and was originally 1.90 from the parts dept.
There are 5 others to choose from,but this looks like what the book calls for.
Any Deuce owners out there care to check?
FYI:My L-78 Chevelle uses a green gear with 42 teeth.
The BEARS!
