X90 "clutch position switch" Questions

[fixkick]

oops/.
are you missing a key part seen as ID #18

The pivot is there. Just looked at pedal arm again and, with clutch pedal .2" above brake pedal, there is 1- 1.5 " of cable between the arm and the metal sheath the cable comes out of. I can push the clutch pedal to floor, releasing clutch, with hands from under dash position so is not too hard. Triple checked everything I can think of and all looks good until I try to adjust nut #19 further on. Cable worked for me before BUT obviously someone had issues before I bought it. It is possible the pedal was set higher originally as I don't remember checking it when I first checked for slack. Had just bought it and didn't have a manual or procedure, just ensured there was some slack in cable.  I am going to need it in a week for a few days so I'm thinking of moving it on the spline at the clutch release lever one tooth and correct it when a new cable comes. I guess it is possible that cable is now catching inside, under tension, but it sure doesn't feel like it.
Is there a burning reason to NOT adjust at clutch arm?

ive done exactly that with wrong parts on car, moved splines, the action of the pedal felt queer but worked.
until good parts arrived./
so long as you can get some free play there, it will not hurt any thing.

one other failure is the wrong  and too thick throw out bearing or was overheated and swelled up (got pregnant),  that bad act kills slack easy.
