> Should there be stops for the brake and clutch pedal?  

Actually, that is a good point.  The factory discontinued installing the
pedal stops at some point, without deleting the holes.  The TRA judging
guidelines give the change point as TS34311, but notes that some later cars
may have been fitted with stops by the factory.

The SPC was never updated to indicate that the stops were removed; but it
also does not show the extra nuts and washers needed to fit the stops to the
later cars with plain holes in the MC mounting bracket.  The earlier cars
had a nut welded on the inside instead of a plain hole, so only a single jam
nut was required (per pedal).

If you do install the stops, it's very important that they still allow some
freeplay in the MC pushrod with the pedal against the stop.  Otherwise the
'foot' valve in the MC may not open to allow excess fluid to return to the
reservoir, which can cause dragging brakes or potentially even a slipping
clutch.  ISTR the book specifies .010" freeplay minimum.
