No, make sure the linkage is properly torqued, and that you can find no kinks in the tubing. They might be subtle, but are noticeable. Yeah, the four bolts that hold up the funky looking bracketing for the shifter itself. loosen those, move the shifter about. Make sure the clutch is in so there's no undue stress when moving the shifter about.
If that doesn't help, see about slightly loosening and re-tightening the tranny mounts. If that still doesn't help, you might have bent the linkage by accident when replacing the clutch, or else a bushing/pivot finally wore out completely.
