Z Bar Spring Clip

The spring clip that wraps around the main tube of the z-bar is intended to lock into the groove in the middle of the pivot bushing on the frame side ball stud. This locks the postion of the z-bar in relation to the frame. The ball stud on the bell housing is allowed to slide in and out with motion of the engine in the motor mounts.

FYI, around 72 the position of the two bolt holes on the sb bell housing for the ball stud bracket moved slightly. If you have issues with the z-bar sitting level and perpendicular to the frame this may be your issue.

There are two different brackets for the two different vintages that is not clearly noted in most references. When I swapped the sb into my 68 cuda I had all sorts of issues with the z-bar not sitting level and sticking under hard acceleration. Wasn't until I talked to Brewers that I learned about the differnt brackets. They sent me the late model on and everything worked perfect.
