    Just thought I'd add this for the archives while the jobs fresh in the
mind and also because I've never seen a clutch MC in a more inaccesible
place in my life. This is the way I did it, may not be the best, but it
worked, and its a million miles from what the Haynes manual suggests (or
fails to). E.g. once you realise the Haynes is well off beam you may wonder
if you have to remove the whole steering coloumn to get the pedal box out. -
The good news is you don't!

N.B. LHD cars are I beleive much easier to work on as they don't have the
crazy relay lever that is a feature of the mad RHD installation. so these
instructions may not make any sense for a LHD car.

    1, Remove cardboard dust cover beneath driver oddments shelf ( 1
selftapper)
    2, Remove Drivers oddments shelf, (3 st's + 1 at back of shelf), Shelf
lowers down on door side but has two bayonet fittings into console side.
    3, Remove brake pedal to pushrod clevis pin.
    4, Remove wiring harness guide plate above brake pedal.(2st's)
    5, Remove Nuts and bolts on either side of steering column lower UJ.
    6, Tap lower steering coloumn up and out of engagement with lower UJ and
upper yoke.
    6a, Remove lower UJ.
    7, Loosen clutch Mc pressure line. (don't fully unscrew for now)
    8, Remove two 13mm nuts at front of pedal box casting, Remove one 13mm
nut to bulkead stud on clutch pivot 'additional bracket'
    9, Remove three 13mm nuts on brake servo to pedal box bracket.
    10, Whilst lowering pedal box carefully, detach bayonet fitting of line
from fluid reservoir from top of MC.
    11, Fully unscrew pressure line to slave cylinder.
    12, Lower and 'manipulate' entire pedal box from car. Try not to get the
pressure line caught up in this.
    13, Take pedal box to bench and replace MC at your comfort.

    14, reassemble in reverse order!, bleeding takes a fair bit of pumping,
I ended up removeing the bleed valve completely to get some flow, and pumped
at least 30 times until it was moving much fluid, then was able to put the
nipple back in and bleed in a more convential manner with willing assistant.
I expect a primed MC would be much easier to bleed but I didn't fancy the
idea of pi*&ing it all over the interior whilst struggling to get the pedal
box back in the car.

    HTH helps someone avoid the headscratching I had over how to go about
this one!
