Buick clutch linkage bushing

[treeboy]

I have a 69 GS400 4-speed. The clutch linkage has rubber bushings in two locations, where the rod from the pedal meets the z-bar (the bushing mounts in the z-bar) and a bushing where the clutch fork meets the rod from the z-bar (the bushing goes in the rod, which connects to the fork with a pin). Does anyone know where these can be sourced from? These are not the little metal or plastic bushings that you can find at the autoparts store, these were rubber bushings (maybe 1/2 inch outside diameter). How about a GM part number for these bushings? Any help would be appreciated.

Same as the 60s Vettes used. I suspect the www.thepartplaceinc.com;

www.yearone.com ; Mike Garrison in Topeka etc.
