Here is a NOS Clutch Pedal shaft that are seriously NLA - no longer available.
I was very desperate in getting my '74/'75 pedal cluster rebuilt and bought this for a ton for money thinking it would work - but it did not so I had to find a used '74.
This is a piece that wears and I don't know if you could find another. For sale for less than I paid.
Porsche part # still on it.
911 423 027 00.
Price is $65 plus shipping, if you want local pickup it's north of Chicago.
Thanks for looking.
I can usually get stuff out in a week depending on work.
