I have a 1980 C-10 and it didn't come w/ the shifter linkage. I recently purchased a linkage from a member. I'm thinkin it attaches to the frame and might need a spring also. Can anyone else confirm this? Right now I have it running from the column to the tranny and it seems like its too loose/flimsy to shift. W/O the linkage, it shifts fine so I know its not the tranny.
