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.
