Tranny linkage adjustment

............ I think those nuts are already staked from the factory and I'm not sure I can adjust them.

Yes, I believe they should be but I'm sure you can force turn them and then re-stake.

If something is stretched, bent, or broken you'll need to pull it out to fix or replace it I think.

Incidentally, if you've been running that disk for some time it will likely be worn more in one area.
