Last time I replaced a clutch one of the disk springs (dampers?) was
broken and, yes, this caused some judder.
Glad you got your problems worked-out, Simon. I admire your tenacity.

you. You may recall from my clutch saga a few years ago that
the replacement parts I received were the issue, although in
my case it was the clutch disc. So I think we must all be
wary of replacement clutches â?? measure everything and compare
old to new. I am told there are companies that will re-face a
