David,
Yoke for the release bearing is held by a pin the shears sometimes, you
would probably have complete failure at that point, but could maybe have a
shard hanging on and making it move with some play?  Also usually three
holes for where the slave hooks with the clevis pin to the extension of the
release bearing shaft, so some mechanical adjustment possible there.

Good luck, as I recall there are also two size bores for the clutch master
or slave (can't remember which) .70" and .75" they should both work, but an
appreciable difference in feel.

That pin to which Greg refers is a taper pin and is shown in this =
picture (not a TR6, but the same idea):

The taper pin is the one on the left with the square head and the hole =
through the head for safety wire.

=20

The other pin at 90 degrees is the way to go if you have these items =
out. It is a =C2=BC=E2=80=9D hardened pin and nyloc nut that is used in =
conjunction with the taper pin.

The cross shaft and fork are drilled together, at right angles to the =
hole for the taper pin. The hole should be a tight fit to avoid any slop =
in the pin/shaft.

=20

Hope this helps.

Dave-

Merry Christmas everyone by the way!

I assume you mean you have the car in gear when you try and start?  I can't=
 think of a cause for it lurching if you are in neutral - but if so I'd thi=
nk its a gearbox issue not a clutch issue.

If you are in gear, only a few things come to mind - 1) you still have air =
in the clutch hydraulics.  2)  If that is unlikely and you see very good tr=
avel on the release arm, then you might have a sheared fork pin as mentione=
d.  Or 3) the clutch disk was installed backwards.  #3 happens unfortunatel=
y to the best of us!

Cheers
Randy
