don't mind at all.
i would suggest doing a search and you will find a ton of info. i am doing the conversion now and will be writing a tech article. superman already has one up for the steel arms (which don't widen the track). difficulty is a matter of degrees so that is hard to answer. i consider myself a novice and i am doing it fine with info from this forum and phone advise from friends. so i would say no hard. expensive, but not hard. doing it right always costs time or money and sometimes both.
