Spring removal is a doddle, dont be afraid, it isnt under any tension until you are wearing the bocks, so it wont hurt you!! Have a look around, I know for a fact, that somewhere, Jason has done a spring removal tutorial!
Also. if you do get the urge to tinker, remove the knee bar/cuff(which ever you have) remove the calf pad, and then the main block holding it all together, inside there are a couple of bolts, check these! Mine were completelt undone! the only reason mine didnt fall off is because the bolt is too long to come out of the hole in the space there is!
This goes for you too Spud! have a look at yours!!
