'84 clutch adjustment, at end of threads

I am at the end of the adjusting threads and clutch still engages about
1-2 inched from end of play- in other words- far from floorboards. I
have no more threads left at tranny end, do I just need a new cable or
can I adjust at pedal end? I read it is just a clevis but are there
not threads on that end too? Thanks!!

One thing that happens is that the cable stretches, especially if it's
the original 20-year-old cable. I'd recommend replacing it before it
breaks and then setting the adjustments back to a normal range.

To (finally!) answer your question, yes, the pedal end is threaded and
it can be adjusted, but the effective adjustment range is small.
Porsche says that you should have 17 to 22mm of threaded cable screwed
into the cable.

Chances are that the real problem here is cable stretch and not adjustments.

there is one other consideration - this happened to me on a 356, but it
might also be possible on a 911 - on the 356A series there is no bushing for
the cross member on which the throwout bearing rides - this is a rod that is
rotated by a lever - you press on teh clutch, a wire pulls the lever
rotating the rod and inside the bell housing a pair of levers holding the
throwout bearing press on the clutch. Anyway, on my car, the holes through
which the rod passes and which form the bearing for the rod enlongated
significantly (on the side with the cable much more than on the other
side) - this caused problems in clutch adjustment, but more nefariously it
also caused the clutch itself to fail in about 6 months with a broken
pressure spring - after maybe a dozen clutches I finally figured it out.
