Had an exciting moment today. Came across this on the internet by coincidence while looking up part numbers for my valve cover gaskets. It's a clutch sleeve kit:

Worn or grooved gearbox "quil" (what the throw out bearing slides on) may be the answer to a number of issues my car has had since this g'box went in. Throw out bearing noise from the moment I put in this gearbox, years ago. Noise goes when pushing clutch in. Opposite to a failed throw out bearing, which was brand new when installed. T/O bearing replaced with DCCD install with no improvement. Shudder on clutch engagement, sometimes. Engagement point on the pedal constantly moving. Jerking on acceleration on/off or changing gears. Creaking on clutch pedal movement, despite lubing the pivot point (and pedal) and a brand new cable.
In prep to solve this issue when I do the motor change I have a complete clutch fork replacement kit and clutch waiting to go in with the new motor. Installed those mustache bar lock bushes. **** if all that didn't fix it I had prepared to move on to a different car because it really effects drive ability.
Never heard of this problem before, ever, and it is apparently common on all 5MTs? Anyway I'm buying it and a big fingers crossed the quil is the problem and this sleeve the fix.
Probably exacerbated by a lack of inspection plate and the housing area been full of dirt, mud and sand on numerous occasions over the years.
For fun i'll link a vid of this kit been installed:
