We have done this conversion several times and it works great. We
also have installed a power servo on several 100/4s so get a stronger
pedal. The only problem with installing a servo is at slow walking
speed you have a very strong pedal.
The only problem with doing the 100/4 conversion is when you
converting a early BN1 the inside diameter of the rear cylinders it
to large and you will not get a strong pedal.
