gas pedal linkage and bushing

I'm having trouble with the linkage from my gas pedal to my offy manifold. Previous owners swapped to the offy with 2 holly 1920, and the peddle is why to stiff. Looks like the rod going through the firewall is not sitting correctly. I think the bushing it goes through my be shot,and the rod dropped 1/4 inch. Anyone ever deal with an issue like that. It is 1965 valiant 200 225 slant.
