Clutch Linkage Spring Clips

Weld them up and re-file them.

I don't know why free-play matters on something that is mechanical, vs. hydraulic. I can understand wanting some confirmation on no action with a hydraulic unit, but a mechanical linkage should set itself out with some sort of spring, or springs, between what's at the dash and at the clutch. Most hydraulic pedals utilize fluid pressure to back off with no additional spring. I've seen some aftermarket brake pedals that use return springs, but very few systems require that or any free-play.

I'd go with the heim joint, but I like really responsive pedals.
