Hello, Should there be any rubber bushings or something on the linkage for the zbar? What I have has been working fine but I just don't like it.
What year do you have? I know 1970 455's has one, not sure about 71-72 and I think 350's maybe different also. maybe some else can help out with the other years.
If you want it be factory correct you will then need an arm with a bushing, it will properly work just fine with the setup you have.
Yes, there's a bushing there. Get one from Racebuicks or from a Corvette supplier: http://v8buick.com/index.php?threads/70-gs-upper-z-bar-bushing.226775/#post-1837489 http://v8buick.com/index.php?threads/pushrod-to-clutch-pedal-bushing-grommet.220249/#post-1776432
