Its not ridiculously hard but it is pretty hard to get the shortened spring back on the clutch. I did a trial run on some a35 clutches a while back and it took me a an hour or so to figure out a "good" way to get it back on. Two people could do it easier, I recommend using a friend with some strong fingers. I had to use clamps to stop the spring from jumping out on one side while Im putting it on on the other side.
Marvyhi, so are you using A3 first gear spring on both clutches? Thanks for your input btw, sounds like you did some serious trials on this thing.
