Most aftermarket throttle and kickdown cables terminate in a ball socket, and if the carburetor lever has the wrong stud, or none, there is nothing to snap that socket onto. This is the 1/4 in. ball end stud for Holley carburetor throttle levers, which is the difference between a linkage that clicks together properly and one that gets improvised.

Edelbrock 8016 Ball End Stud Details:

• 1/4 in. ball end throttle lever stud.
• For Holley carburetors, threading into the throttle lever.
• Accepts standard ball socket throttle and transmission kickdown cable ends.
• Sold individually, so order the quantity your linkage requires.
