John,

I don't know what clutch/Flywheel combination was used with your A-type OD,
but make sure you have the shorter Front cover (the nose, inside the
bellhousing) if you use the later Diaphragm clutch.  The earlier trannies
has the longer nose, which may foul and destroy the diaphragm clutch
fingers.  The Moss catalog has the dimensions,  The later one is shorter.
